     Before including this file, define a macro:
  
! 	AVR_MCU (NAME, ARCH, ATTR, MACRO, TDATA, TTEXT, FLASH_SIZE, PM_OFFSET)
  
     where the arguments are the fields of avr_mcu_t:
     
! 	NAME	Name of the device as specified by -mmcu=<NAME>.  Also
! 		used by DRIVER_SELF_SPECS and gen-avr-mmcu-specs.c for
! 		- the name of the device specific specs file
! 		  in -specs=device-specs/spec-<NAME>
! 		- the name of the startup file crt<NAME>.o
! 		- the name of the device library to be linked with -l<NAME>
  
! 	ARCH	Specifies the multilib variant together with AVR_SHORT_SP
  
! 	ATTR	Specifies the device specific features
! 		- additional ISA, short SP, errata skip etc.,
  
! 	MACRO	If NULL, this is a core and not a device.  If non-NULL,
! 		supply respective built-in macro.
  
! 	TDATA	First address of SRAM, used in -Tdata=<DATA_START>.
  
! 	TTEXT	First address of Flash, used in -Ttext=<TEXT_START>.
  
! 	FLASH_SIZE
! 		Flash size in bytes.
! 
! 	PM_OFFSET
! 		Either 0x0 or the offset where flash memory is mirrored
! 		into the RAM address space accessible by LD, LDD and LDS.
! 		This is only needed if that value deviates from the
! 		value for the respective device family.
  
     "avr2" must be first for the "0" default to work as intended.  */

       '-Werror' are controlled by the Makefiles.
  
  '--enable-checking'
  '--enable-checking=LIST'
!      When you specify this option, the compiler is built to perform
!      internal consistency checks of the requested complexity.  This does
!      not change the generated code, but adds error checking within the
!      compiler.  This will slow down the compiler and may only work
!      properly if you are building the compiler with GCC.  This is
!      'yes,extra' by default when building from SVN or snapshots, but
!      'release' for releases.  The default for building the stage1
!      compiler is 'yes'.  More control over the checks may be had by
!      specifying LIST.  The categories of checks available are 'yes'
!      (most common checks 'assert,misc,tree,gc,rtlflag,runtime'), 'no'
       (no checks at all), 'all' (all but 'valgrind'), 'release' (cheapest
!      checks 'assert,runtime') or 'none' (same as 'no').  Individual
!      checks can be enabled with these flags 'assert', 'df', 'fold',
!      'gc', 'gcac', 'misc', 'rtl', 'rtlflag', 'runtime', 'tree', 'extra'
!      and 'valgrind'.  'extra' adds for 'misc' checking extra checks that
!      might affect code generation and should therefore not differ
!      between stage1 and later stages.
  
       The 'valgrind' check requires the external 'valgrind' simulator,
!      available from <http://valgrind.org/>.  The 'df', 'rtl', 'gcac' and
!      'valgrind' checks are very expensive.  To disable all checking,
!      '--disable-checking' or '--enable-checking=none' must be explicitly
!      requested.  Disabling assertions will make the compiler and runtime
!      slightly faster but increase the risk of undetected internal errors

  '--disable-stage1-checking'
  '--enable-stage1-checking'
  '--enable-stage1-checking=LIST'
!      If no '--enable-checking' option is specified the stage1 compiler
!      will be built with 'yes' checking enabled, otherwise the stage1
!      checking flags are the same as specified by '--enable-checking'.
!      To build the stage1 compiler with different checking options use
       '--enable-stage1-checking'.  The list of checking options is the
       same as for '--enable-checking'.  If your system is too slow or too
       small to bootstrap a released compiler with checking for stage1

  '--enable-checking'
+ '--disable-checking'
  '--enable-checking=LIST'
!      This option controls performing internal consistency checks in the
!      compiler.  It does not change the generated code, but adds error
!      checking of the requested complexity.  This slows down the compiler
!      and may only work properly if you are building the compiler with
!      GCC.
! 
!      When the option is not specified, the active set of checks depends
!      on context.  Namely, bootstrap stage 1 defaults to
!      '--enable-checking=yes', builds from release branches or release
!      archives default to '--enable-checking=release', and otherwise
!      '--enable-checking=yes,extra' is used.  When the option is
!      specified without a LIST, the result is the same as
!      '--enable-checking=yes'.  Likewise, '--disable-checking' is
!      equivalent to '--enable-checking=no'.
! 
!      The categories of checks available in LIST are 'yes' (most common
!      checks 'assert,misc,gc,gimple,rtlflag,runtime,tree,types'), 'no'
       (no checks at all), 'all' (all but 'valgrind'), 'release' (cheapest
!      checks 'assert,runtime') or 'none' (same as 'no').  'release'
!      checks are always on and to disable them '--disable-checking' or
!      '--enable-checking=no[,<other checks>]' must be explicitly
!      requested.  Disabling assertions makes the compiler and runtime
!      slightly faster but increases the risk of undetected internal
!      errors causing wrong code to be generated.
! 
!      Individual checks can be enabled with these flags: 'assert', 'df',
!      'extra', 'fold', 'gc', 'gcac', 'gimple', 'misc', 'rtl', 'rtlflag',
!      'runtime', 'tree', 'types' and 'valgrind'.  'extra' extends 'misc'
!      checking with extra checks that might affect code generation and
!      should therefore not differ between stage1 and later stages in
!      bootstrap.
  
       The 'valgrind' check requires the external 'valgrind' simulator,
!      available from <http://valgrind.org/>.  The 'rtl' checks are
!      expensive and the 'df', 'gcac' and 'valgrind' checks are very
!      expensive.
  
  '--disable-stage1-checking'
  '--enable-stage1-checking'
  '--enable-stage1-checking=LIST'
!      This option affects only bootstrap build.  If no
!      '--enable-checking' option is specified the stage1 compiler is
!      built with 'yes' checking enabled, otherwise the stage1 checking
!      flags are the same as specified by '--enable-checking'.  To build
!      the stage1 compiler with different checking options use
       '--enable-stage1-checking'.  The list of checking options is the
       same as for '--enable-checking'.  If your system is too slow or too
       small to bootstrap a released compiler with checking for stage1

     The solution is not to use such a directory for building GCC.

+      Some C interfaces to Fortran codes violate the gfortran ABI by
+      omitting the hidden character length arguments as described in
+      *Note Argument passing conventions::.  This can lead to crashes
+      because pushing arguments for tail calls can overflow the stack.
+ 
+      To provide a workaround for existing binary packages, this option
+      disables tail call optimization for gfortran procedures with
+      character arguments.  With '-ftail-call-workaround=2' tail call
+      optimization is disabled in all gfortran procedures with character
+      arguments, with '-ftail-call-workaround=1' or equivalent
+      '-ftail-call-workaround' only in gfortran procedures with character
+      arguments that call implicitly prototyped procedures.
+ 
+      Using this option can lead to problems including crashes due to
+      insufficient stack space.
+ 
+      It is _very strongly_ recommended to fix the code in question.  The
+      '-fc-prototypes-external' option can be used to generate prototypes
+      which conform to gfortran's ABI, for inclusion in the source code.
+ 
+      Support for this option will likely be withdrawn in a future
+      release of gfortran.
+ 
+      The negative form, '-fno-tail-call-workaround' or equivalent
+      '-ftail-call-workaround=0', can be used to disable this option.
+ 
+      Default is currently '-ftail-call-workaround', this will change in
+      future releases.

+ Some C interfaces to Fortran codes violate the gfortran ABI by
+ omitting the hidden character length arguments as described in
+ @xref{Argument passing conventions}.  This can lead to crashes
+ because pushing arguments for tail calls can overflow the stack.
+ 
+ To provide a workaround for existing binary packages, this option
+ disables tail call optimization for gfortran procedures with character
+ arguments.  With @option{-ftail-call-workaround=2} tail call optimization
+ is disabled in all gfortran procedures with character arguments,
+ with @option{-ftail-call-workaround=1} or equivalent
+ @option{-ftail-call-workaround} only in gfortran procedures with character
+ arguments that call implicitly prototyped procedures.
+ 
+ Using this option can lead to problems including crashes due to
+ insufficient stack space.
+ 
+ It is @emph{very strongly} recommended to fix the code in question.
+ The @option{-fc-prototypes-external} option can be used to generate
+ prototypes which conform to gfortran's ABI, for inclusion in the
+ source code.
+ 
+ Support for this option will likely be withdrawn in a future release
+ of gfortran.
+ 
+ The negative form, @option{-fno-tail-call-workaround} or equivalent
+ @option{-ftail-call-workaround=0}, can be used to disable this option.
+ 
+ Default is currently @option{-ftail-call-workaround}, this will change
+ in future releases.

+  * <p>
+  *   The standard OpenStep system of memory management employs retain counts.
+  *   When an object is created, it has a retain count of 1.  When an object
+  *   is retained, the retain count is incremented.  When it is released the
+  *   retain count is decremented, and when the retain count goes to zero the
+  *   object gets deallocated.
+  * </p>
+  * <p>
+  *   A simple retain/release mechanism has problems with passing objects
+  *   from one scope to another,
+  *   so it's augmented with autorelease pools.  You can use the
+  *   AUTORELEASE() macro to call the [NSObject-autorelease]
+  *   method, which adds an object to the current autorelease pool by
+  *   calling [NSAutoreleasePool+addObject:].<br />
+  *   An autorelease pool simply maintains a reference to each object
+  *   added to it, and for each addition, the autorelease pool will
+  *   call the [NSObject-release] method of the object when the pool
+  *   is released.  So doing an AUTORELEASE() is just the same as
+  *   doing a RELEASE(), but deferred until the current autorelease
+  *   pool is deallocated.
+  * </p>
+  * <p>
+  *   The NSAutoreleasePool class maintains a separate stack of
+  *   autorelease pools objects in each thread.
+  * </p>
+  * <p>
+  *   When an autorelease pool is created, it is automatically
+  *   added to the stack of pools in the thread.
+  * </p>
+  * <p>
+  *   When a pool is destroyed, it (and any pool later in
+  *   the stack) is removed from the stack.
+  * </p>
+  * <p>
+  *   This mechanism provides a simple but controllable and reasonably
+  *   efficient way of managing temporary objects.  An object can be
+  *   autoreleased and then passed around and used until the topmost 
+  *   pool in the stack is destroyed.
+  * </p>   
+  * <p>
+  *   Most methods return objects which are either owned by autorelease
+  *   pools or by the receiver of the method, so the lifetime of the
+  *   returned object can be assumed to be the shorter of the lifetime
+  *   of the current autorelease pool, or that of the receiver on which
+  *   the method was called.<br />

+ <chapter>
+  <heading>Portable path handling</heading>
+  <p>Portable path handling (across both unix-like and mswindows operating
+  systems) requires some care.  A modern operating system uses the concept
+  of a single root to the filesystem, but mswindows has multiple filesystems
+  with no common root, so code must be aware of this.  There is also the
+  more minor issue that windows often uses a backslash as a separator between
+  the components of a path and unix-like systems always use forward slash.<br />
+  On windows there is also the issue that two styles of path are used,
+  most commonly with a drive letter and a path on that drive
+  (eg. 'C:\directory\file') but also UNC paths
+  (eg. '//host/share/directory/file') so path handling functions must deal
+  with both formats.
+  </p>
+  <p>GNUstep has three path handling modes, 'gnustep', 'unix', and 'windows'.
+  The mode defaults to 'gnustep' but may be set using the GSPathHandling()
+  function.<br />
+  You should probably stick to using the default 'gnustep' mode in which the
+  path handling methods cope with both 'unix' and 'windows' style paths in
+  portable and tolerant manner:<br />
+  Paths are read in literally so they can be in the native format provided
+  by the operating system or in a non-native format. See
+  [NSFileManager-stringWithFileSystemRepresentation:length:].<br />
+  Paths are written out using the native format of the system the application
+  is running on (eg on windows slashes are converted to backslashes).
+  See [NSFileManager-fileSystemRepresentationWithPath:].<br />
+  The path handling methods accept either a forward or backward slash as a
+  path separator when parsing any path.<br />
+  Unless operating in 'unix' mode, a leading letter followed by a colon is
+  considered the start of a windows style path (the drive specifier), and a
+  path beginning with something of the form '//host/share/' is considered
+  the start of a UNC style path.<br />
+  The path handling methods add forward slashes when building new paths
+  internally or when standardising paths, so those path strings provide
+  a portable representation (as long as they are relative paths, not including
+  system specific roots).<br />
+  An important case to note is that on windows a path which looks at first
+  glance like an absolute path may actually be a relative one.<br />
+  'C:file' is a relative path because it specifies  a file on the C drive
+  but does not say what directory it is in.<br />
+ Similarly, '/dir/file' is a relative path because it specifies the full
+ location fo a file on a drive, but does not specify which drive it is on.
+  </p>
+ <p>As a consequence of this path handling, you are able to work completely
+ portably using relative paths (adding components, extensions and
+ relative paths to a pth, or removing components, extensions and relative
+ paths from a path etc), and when you save paths as strings in files
+ which may be transferred to another platform, you should save a relative
+ path.<br />
+ When you need to know absolute paths of various points in the filesystem,
+ you can use various path utility functions to obtain those absolute paths.
+ For instance, instead of saving an absolute path to a file, you might want
+ to save a path relative to a user's home directory.  You could do that by
+ calling NSHomeDirectory() to get the home directory, and only saving the
+ part of the full path after that prefix.
+ </p>

+  *   <code>NSString</code> objects represent an immutable string of Unicode 3.0
+  *   characters.  These may be accessed individually as type
+  *   <code>unichar</code>, an unsigned short.<br/>
+  *   The [NSMutableString] subclass represents a modifiable string.  Both are
+  *   implemented as part of a class cluster and the instances you receive may
+  *   actually be of unspecified concrete subclasses.
+  * </p>
+  * <p>
+  *   A constant <code>NSString</code> can be created using the following syntax:
+  *   <code>@"..."</code>, where the contents of the quotes are the
+  *   string, using only ASCII characters.
+  * </p>
+  * <p>
+  *   A variable string can be created using a C printf-like <em>format</em>,
+  *   as in <code>[NSString stringWithFormat: @"Total is %f", t]</code>.
+  * </p>
+  * <p>
+  *   To create a concrete subclass of <code>NSString</code>, you must have your
+  *   class inherit from <code>NSString</code> and override at least the two
+  *   primitive methods - -length and -characterAtIndex:
+  * </p>
+  * <p>
+  *   In general the rule is that your subclass must override any
+  *   initialiser that you want to use with it.  The GNUstep
+  *   implementation relaxes that to say that, you may override
+  *   only the <em>designated initialiser</em> and the other
+  *   initialisation methods should work.
+  * </p>
+  * <p>
+  *   Where an NSString instance method returns an NSString object,
+  *   the class of the actual object returned may be any subclass
+  *   of NSString.  The actual value returned may be a new
+  *   autoreleased object, an autoreleased copy of the receiver,
+  *   or the receiver itsself.  While the abstract base class
+  *   implementations of methods (other than initialisers) will
+  *   avoid returning mutable strings by returning an autoreleased
+  *   copy of a mutable receiver, concrete subclasses may behave
+  *   differently, so code should not rely upon the mutability of
+  *   returned strings nor upon their lifetime being greater than
+  *   that of the receiver which returned them.

+  *   to localize from the <code>GSLocalizedStaticString</code>
+  *   call.

+  * <p>
+  *   When the code is compiled, instead, the
+  *   <code>GSLocalizedStaticString</code> call is ignored (discarded,
+  *   it is a macro which simply expands to <code>key</code>), while
+  *   the <code>NSLocalizedString</code> will actually look up the
+  *   string for translation in the <code>Localizable.strings</code>
+  *   file.
+  * </p>
+  * <p>
+  *   Please note that there is currently no macro/function to
+  *   localize static strings using different tables.  If you
+  *   need that functionality, you have either to prepare the

!   There are various third party memory tracing and debug utilities
    that can be used to provide detailed memory allocation information
    about C++ code. An exhaustive list of tools is not going to be
    attempted, but includes <code class="code">mtrace</code>, <code class="code">valgrind</code>,
!   <code class="code">mudflap</code>, and the non-free commercial product
!   <code class="code">purify</code>. In addition, <code class="code">libcwd</code> has a
!   replacement for the global new and delete operators that can track
!   memory allocation and deallocation and provide useful memory
!   statistics.
! </p><p>
!   Regardless of the memory debugging tool being used, there is one
!   thing of great importance to keep in mind when debugging C++ code
!   that uses <code class="code">new</code> and <code class="code">delete</code>: there are
!   different kinds of allocation schemes that can be used by <code class="code">
!   std::allocator</code>. For implementation details, see the <a class="link" href="mt_allocator.html" title="Chapter 20. The mt_allocator">mt allocator</a> documentation and
!   look specifically for <code class="code">GLIBCXX_FORCE_NEW</code>.
! </p><p>
!   In a nutshell, the optional <code class="classname">mt_allocator</code>
!   is a high-performance pool allocator, and can
!   give the mistaken impression that in a suspect executable, memory is
!   being leaked, when in reality the memory "leak" is a pool being used
!   by the library's allocator and is reclaimed after program
!   termination.
  </p><p>
    For valgrind, there are some specific items to keep in mind. First
    of all, use a version of valgrind that will work with current GNU
    C++ tools: the first that can do this is valgrind 1.0.4, but later
!   versions should work at least as well. Second of all, use a
!   completely unoptimized build to avoid confusing valgrind. Third, use
!   GLIBCXX_FORCE_NEW to keep extraneous pool allocation noise from
!   cluttering debug information.
  </p><p>
!   Fourth, it may be necessary to force deallocation in other libraries
!   as well, namely the "C" library. On linux, this can be accomplished
    with the appropriate use of the <code class="code">__cxa_atexit</code> or
    <code class="code">atexit</code> functions.

!     Since GCC 5.1.0, libstdc++ automatically allocates a pool
!     of a few dozen kilobytes on startup. This pool is used to ensure it's
!     possible to throw exceptions (such as <classname>bad_alloc</classname>)

!     this pool will be shown as "still reachable" when the process exits, e.g.
!     <code>still reachable: 72,704 bytes in 1 blocks</code>.
!     This memory is not a leak, because it's still in use by libstdc++,
!     and the memory will be returned to the OS when the process exits.
!     Later versions of <command>valgrind</command> know how to free this

  <para>
!   There are various third party memory tracing and debug utilities
    that can be used to provide detailed memory allocation information
    about C++ code. An exhaustive list of tools is not going to be
    attempted, but includes <code>mtrace</code>, <code>valgrind</code>,
!   <code>mudflap</code>, and the non-free commercial product
!   <code>purify</code>. In addition, <code>libcwd</code> has a
!   replacement for the global new and delete operators that can track
!   memory allocation and deallocation and provide useful memory
!   statistics.
! </para>
! 
! <para>
!   Regardless of the memory debugging tool being used, there is one
!   thing of great importance to keep in mind when debugging C++ code
!   that uses <code>new</code> and <code>delete</code>: there are
!   different kinds of allocation schemes that can be used by <code>
!   std::allocator</code>. For implementation details, see the <link linkend="manual.ext.allocator.mt">mt allocator</link> documentation and
!   look specifically for <code>GLIBCXX_FORCE_NEW</code>.
! </para>
! 
! <para>
!   In a nutshell, the optional <classname>mt_allocator</classname>
!   is a high-performance pool allocator, and can
!   give the mistaken impression that in a suspect executable, memory is
!   being leaked, when in reality the memory "leak" is a pool being used
!   by the library's allocator and is reclaimed after program
!   termination.
  </para>
  
  <para>
    For valgrind, there are some specific items to keep in mind. First
    of all, use a version of valgrind that will work with current GNU
    C++ tools: the first that can do this is valgrind 1.0.4, but later
!   versions should work at least as well. Second of all, use a
!   completely unoptimized build to avoid confusing valgrind. Third, use
!   GLIBCXX_FORCE_NEW to keep extraneous pool allocation noise from
!   cluttering debug information.
  </para>
  
  <para>
!   Fourth, it may be necessary to force deallocation in other libraries
!   as well, namely the "C" library. On linux, this can be accomplished
    with the appropriate use of the <code>__cxa_atexit</code> or
    <code>atexit</code> functions.

+ # Libtool notes
+ 
+ # 1) In general, libtool expects an argument such as `--tag=CXX' when
+ # using the C++ compiler, because that will enable the settings
+ # detected when C++ support was being configured.  However, when no
+ # such flag is given in the command line, libtool attempts to figure
+ # it out by matching the compiler name in each configuration section
+ # against a prefix of the command line.  The problem is that, if the
+ # compiler name and its initial flags stored in the libtool
+ # configuration file don't match those in the command line, libtool
+ # can't decide which configuration to use, and it gives up.  The
+ # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
+ # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
+ # attempt to infer which configuration to use.
+ #
+ # The second tag argument, `--tag disable-shared` means that libtool
+ # only compiles each source once, for static objects. In actuality,
+ # glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
+ # the libtool command that is used create the object, which is
+ # suitable for shared libraries.  The `--tag disable-shared` must be
+ # placed after --tag CXX lest things CXX undo the affect of
+ # disable-shared.
+ 
+ # 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
+ # last. (That way, things like -O2 passed down from the toplevel can
+ # be overridden by --enable-debug.)

+ # the rules automake generates would be used.  We cannot allow g++ to
+ # be used since this would add -lstdc++ to the link line which of
+ # course is problematic at this point.  So, we get the top-level
