I've only been eyeballing this and the other thread, but I think the conditional we're looking for is: #if defined(__BSD_VISIBLE) || (defined(__POSIX_VISIBLE) && defined(_REENTRANT)) This provides the reentrant functions in the unencumbered (no standard specified) namespace and in the POSIX namespace when requested.
