Hey everyone, I'm trying to use the function rand_r with gcc-4 in Cygwin 1.7, all my packages are up to date. It's supposed to be defined in stdlib.h, and I can see it there. But if I compile a program which uses it, I get: warning: implicit declaration of function 'rand_r'. The reason seems to be the check for #ifndef __STRICT_ANSI__ in stdlib.h. Even though I'm compiling with -std=c99, __STRICT_ANSI__ still gets declared, so the definition of rand_r is unavailable. This seems to be the same problem stated here: http://sourceware.org/ml/newlib/2007/msg00783.html Is this a bug or is rand_r supposed to be unavailable with C99?
