[PATCH] Fix i386 bits/mathinline.h with -ansi -pedantic

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

Without this, programs including math.h compiled with -ansi -pedantic don't
compile (?: with omitted middle part gives a warning, while the latter
construct results in error).

2000-05-22  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/i386/fpu/bits/mathinline.h (__expm1_code): Avoid using ?:
	with omitted middle operand.
	(__sgn1l): Add __extension__.
