32bit doesnt get -D_GNU_SOURCE from pkg-config while 64 does here the prototypes are under #ifdef __USE_GNU [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Complexity theory is the science of finding the exact solution to an approximation. Benchmarking OTOH is finding an approximation of the exact
