Hi! If math.h is included in some file which is compiled with -pedantic by gcc 2.95+, one gets an error. __extension__ helps here. 2000-05-17 Jakub Jelinek <jakub@redhat.com> * sysdeps/arm/bits/huge_val.h (HUGE_VAL, HUGE_VALF): Add __extension__ to hexadecimal floating constant notation. * sysdeps/i386/bits/huge_val.h (HUGE_VAL, HUGE_VALF, HUGE_VALL): Likewise. * sysdeps/ieee754/bits/huge_val.h (HUGE_VAL, HUGE_VALF): Likewise. * sysdeps/m68k/bits/huge_val.h (HUGE_VAL, HUGE_VALF, HUGE_VALL): Likewise. * sysdeps/sparc/sparc64/bits/huge_val.h (HUGE_VAL, HUGE_VALF, HUGE_VALL): Likewise. * sysdeps/sparc/sparc32/bits/huge_val.h (HUGE_VAL, HUGE_VALF, HUGE_VALL): Likewise.
