Hi Paul,
In compiling coreutils with -std=gnu99, I see this new warning:
xstrtod.c:33: warning: ignoring #pragma STDC FENV_ACCESS
Why was this code needed?
/* Tell the compiler that non-default rounding modes are used. */
#if 199901 <= __STDC_VERSION__
#pragma STDC FENV_ACCESS ON
#endif
The warning makes me think it's not useful -- at least not with
gcc and -std=gnu99.
- c99+ pragma is ignored by gcc -std=gnu99,
