Subject: [PATCH] SDL_config_unix.h: Assume we have complete POSIX
functionality
Classic SDL2 checked for these functions at compile-time and defined
the corresponding macros if found. According to the man pages on my
Linux system, these were all specified in POSIX.1-2008 or older, so
they seem like they ought to be a safe assumption.
