A _POSIX_C_SOURCE definition is needed for some locale definitions, but
some non-standard functions are also used (notably futimes). Avoid using
a global definition for _POSIX_C_SOURCE and define it where necessary,
while also defining _BSD_SOURCE and _NETBSD_SOURCE to get the right
prototype for futimes where necessary.
Libretro is a simple but powerful development interface that allows for the
easy creation of emulators, games and multimedia applications that can plug
straight into any libretro-compatible frontend. This development interface is
open to others so that they can run these pluggable emulator and game cores
also in their own programs or devices.
mGBA is an emulator for running Game Boy Advance games. It aims to be faster
and more accurate than many existing Game Boy Advance emulators, as well as
adding features that other emulators lack. It also supports Game Boy and
Game Boy Color games.
