   dnl  Can we say ".type", and how?
   dnl
   dnl  For i386 GNU/Linux ELF systems, and very likely other ELF systems,
   dnl  .type and .size are important on functions in shared libraries.  If
   dnl  .type is omitted and the mainline program references that function then
   dnl  the code will be copied down to the mainline at load time like a piece
   dnl  of data.  If .size is wrong or missing (it defaults to 4 bytes or some
   dnl  such) then incorrect bytes will be copied and a segv is the most likely
   dnl  result.  In any case such copying is not what's wanted, a .type
   dnl  directive will ensure a PLT entry is used.
   dnl
   dnl  In GMP the assembler functions are normally only used from within the
   dnl  library (since most programs are not interested in the low level
   dnl  routines), and in those circumstances a missing .type isn't fatal,
   dnl  letting the problem go unnoticed.  tests/mpn/t-asmtype.c aims to check
   dnl  for it.

   dnl  ------------------
   dnl  Find out how to call mcount for profiling on an x86 system.
   dnl
   dnl  A dummy function is compiled and the ".s" output examined.  The pattern
   dnl  matching might be a bit fragile, but should work at least with gcc on
   dnl  sensible systems.  Certainly it's better than hard coding a table of
   dnl  conventions.
   dnl
   dnl  For non-PIC, any ".data" is taken to mean a counter might be passed.
   dnl  It's assumed a movl will set it up, and the right register is taken
   dnl  from that movl.  Any movl involving %esp is ignored (a frame pointer
   dnl  setup normally).
   dnl
   dnl  For PIC, any ".data" is similarly interpreted, but a GOTOFF identifies
   dnl  the line setting up the right register.
   dnl
   dnl  In both cases a line with "mcount" identifies the call and that line is
   dnl  used literally.
   dnl
   dnl  On some systems (eg. FreeBSD 3.5) gcc emits ".data" but doesn't use it,
   dnl  so it's not an error to have .data but then not find a register.
   dnl
   dnl  Variations in mcount conventions on different x86 systems can be found
   dnl  in gcc config/i386.  mcount can have a "_" prefix or be .mcount or
   dnl  _mcount_ptr, and for PIC it can be called through a GOT entry, or via
   dnl  the PLT.  If a pointer to a counter is required it's passed in %eax or
   dnl  %edx.
   dnl
   dnl  Flags to specify PIC are taken from $lt_prog_compiler_pic set by
   dnl  AC_PROG_LIBTOOL.
   dnl
   dnl  Enhancement: Cache the values determined here. But what's the right way
   dnl  to get two variables (mcount_nonpic_reg and mcount_nonpic_call say) set
   dnl  from one block of commands?

   #
   # Of course, Automake must honor this variable whenever it calls a
   # tool from the auxiliary directory.  The problem is that $srcdir (and
   # therefore $ac_aux_dir as well) can be either absolute or relative,
   # depending on how configure is run.  This is pretty annoying, since
   # it makes $ac_aux_dir quite unusable in subdirectories: in the top
   # source directory, any form will work fine, but in subdirectories a
   # relative path needs to be adjusted first.
   #
   # $ac_aux_dir/missing
   #    fails when called from a subdirectory if $ac_aux_dir is relative
   # $top_srcdir/$ac_aux_dir/missing
   #    fails if $ac_aux_dir is absolute,
   #    fails when called from a subdirectory in a VPATH build with
   #          a relative $ac_aux_dir
   #
   # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
   # are both prefixed by $srcdir.  In an in-source build this is usually
   # harmless because $srcdir is `.', but things will broke when you
   # start a VPATH build or use an absolute $srcdir.
   #
   # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
   # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
   #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
   # and then we would define $MISSING as
   #   MISSING="\${SHELL} $am_aux_dir/missing"
   # This will work as long as MISSING is not called from configure, because
   # unfortunately $(top_srcdir) has no meaning in configure.
   # However there are other variables, like CC, which are often used in
   # configure, and could therefore not use this "fixed" $ac_aux_dir.
