Without this, GNU-specific symbols won't be defined and the compiler check will pass because GCC will assume that you know what you're doing since it doesn't know what the symbol prototype is and compiler checks aren't built with -Wall -Werror. This will then cause a build failure because the wrong prototype will be used.
