+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  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  ansi2knr is used.  A C++ compiler fails on the K&R part, which makes
-dnl  AM_C_PROTOTYPES think it needs ansi2knr!  GMP has no bare K&R so we

+#    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.
