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.
