Grep's not a good way to check. Glibc uses a lot of preprocessor macros. <bits/mathcalls.h>: #ifdef __USE_ISOC99 ... /* Round X to nearest integral value, rounding halfway cases away from zero. */ __MATHCALLX (round,, (_Mdouble_ __x), (__const__)); Try using -D_GNU_SOURCE and then see if it's there. Or -D_ISOC99_SOURCE, or gcc -std=c99. -- Daniel Jacobowitz MontaVista Software Debian GNU/Linux Developer
