Hi! Sadly it turns out that eventhough gcc 2.95 handles hex floating constants just fine (with __extension__ for -pedantic), g++ 2.95 does not, so everyone now gets a fatal error including math.h in a C++ program. Fortunately g++ 2.96 does (ObjC did already in 2.95), so IMHO we have three choices: - simply prereq 2.96 like done with this patch - use # if __GNUC_PREREQ(2,96) || (__GNUC_PREREQ(2,95) && !defined(__cplusplus)) - kill the hex floating consts bits from huge_val.h 2000-05-21 Jakub Jelinek <jakub@redhat.com> * sysdeps/arm/bits/huge_val.h: Prereq gcc 2.96+, not 2.95. * sysdeps/i386/bits/huge_val.h: Likewise. * sysdeps/ieee754/bits/huge_val.h: Likewise. * sysdeps/m68k/bits/huge_val.h: Likewise. * sysdeps/sparc/sparc32/bits/huge_val.h: Likewise. * sysdeps/sparc/sparc64/bits/huge_val.h: Likewise. --- libc/sysdeps/arm/bits/huge_val.h.jj Thu May 18 14:49:54 2000 +++ libc/sysdeps/arm/bits/huge_val.h Sun May 21 06:23:09 2000 @@ -29,7 +29,7 @@ #ifdef __GNUC__ -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VAL (__extension__ 0x1.0p2047) @@ -67,7 +67,7 @@ static __huge_val_t __huge_val = { __HUG # ifdef __GNUC__ -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VALF (__extension__ 0x1.0p255f) --- libc/sysdeps/i386/bits/huge_val.h.jj Thu May 18 14:50:03 2000 +++ libc/sysdeps/i386/bits/huge_val.h Sun May 21 06:23:09 2000 @@ -26,7 +26,7 @@ /* IEEE positive infinity (-HUGE_VAL is negative infinity). */ -#if __GNUC_PREREQ(2,95) +#if __GNUC_PREREQ(2,96) # define HUGE_VAL (__extension__ 0x1.0p2047) #else # define __HUGE_VAL_bytes { 0, 0, 0, 0, 0, 0, 0xf0, 0x7f } @@ -46,7 +46,7 @@ static __huge_val_t __huge_val = { __HUG #ifdef __USE_ISOC99 -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VALF (__extension__ 0x1.0p255f) # define HUGE_VALL (__extension__ 0x1.0p32767L) --- libc/sysdeps/ieee754/bits/huge_val.h.jj Thu May 18 14:50:05 2000 +++ libc/sysdeps/ieee754/bits/huge_val.h Sun May 21 06:23:09 2000 @@ -28,7 +28,7 @@ #ifdef __GNUC__ -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VAL (__extension__ 0x1.0p2047) @@ -66,7 +66,7 @@ static __huge_val_t __huge_val = { __HUG # ifdef __GNUC__ -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VALF (__extension__ 0x1.0p255f) --- libc/sysdeps/m68k/bits/huge_val.h.jj Thu May 18 14:50:07 2000 +++ libc/sysdeps/m68k/bits/huge_val.h Sun May 21 06:23:09 2000 @@ -30,7 +30,7 @@ #ifdef __GNUC__ -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VAL (__extension__ 0x1.0p2047) @@ -56,7 +56,7 @@ static union { unsigned char __c[8]; dou #ifdef __USE_ISOC99 -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VALF (__extension__ 0x1.0p255f) # define HUGE_VALL (__extension__ 0x1.0p32767L) --- libc/sysdeps/sparc/sparc32/fpu/bits/huge_val.h.jj Thu May 18 14:50:19 2000 +++ libc/sysdeps/sparc/sparc32/fpu/bits/huge_val.h Sun May 21 06:23:09 2000 @@ -29,7 +29,7 @@ #ifdef __GNUC__ -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VAL (__extension__ 0x1.0p2047) @@ -58,7 +58,7 @@ static __huge_val_t __huge_val = { __HUG #ifdef __USE_ISOC99 -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VALF (__extension__ 0x1.0p255f) # if __WORDSIZE == 32 --- libc/sysdeps/sparc/sparc64/fpu/bits/huge_val.h.jj Thu May 18 14:50:21 2000 +++ libc/sysdeps/sparc/sparc64/fpu/bits/huge_val.h Sun May 21 06:23:09 2000 @@ -29,7 +29,7 @@ #ifdef __GNUC__ -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VAL (__extension__ 0x1.0p2047) @@ -58,7 +58,7 @@ static __huge_val_t __huge_val = { __HUG #ifdef __USE_ISOC99 -# if __GNUC_PREREQ(2,95) +# if __GNUC_PREREQ(2,96) # define HUGE_VALF (__extension__ 0x1.0p255f) # if __WORDSIZE == 32 Jakub
