>Description:
	When building the "bleeding edge" Perl release, I get the
	following message:

	CCCMD =  gcc -DPERL_CORE -c -fno-strict-aliasing -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm -O -Wall
	`sh  cflags "optimize='-O'" pp_pack.o`  pp_pack.c
	CCCMD =  gcc -DPERL_CORE -c -fno-strict-aliasing -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm -O -Wall
	/tmp/ccjyyLrj.s: Assembler messages:
	/tmp/ccjyyLrj.s:2477: Error: no such 386 instruction: `filds'
	/tmp/ccjyyLrj.s:6793: Error: no such 386 instruction: `fistps'
	make: *** [pp_pack.o] Error 1

>How-To-Repeat:
	Get the perl tarball (from ftp://ftp.funet.fi/pub/languages/perl/snap/).
	The version that triggered the error was perl_4016694.tgz, but
	I doubt that the particular version matters much (pp_pack.c
	hasn't changed recently).  Configure it on an intel box.
	(Some expertise in bleeding edge perl would be useful here, but
	sh Configure -Dprefix=/opt/perl \
		-Dusedevel \
		-Duse64bitall \
		-Duseperlio \
		-Dinstallusrbinperl=n
	will probably do.)  I tried various compiler options,
	including -gstabs and -mcpu=i686, but the error persists.

	Perl version 5.8 is about to be released, and will be
	close to the "bleeding edge" version, so it would be
	nice if it could be built with the 3.1 compiler.
	(It builds fine with the 2.96 compiler).
