-- This is necessary, otherwise compilation will fail since
-- there is no CLOCK_MONOTOMIC. raylib claims to have a workaround
-- to compile under c99 without -D_GNU_SOURCE, but it didn't seem
-- to work. raylib's Makefile also adds this flag, probably why it went
-- unnoticed for so long.
-- It compiles under c11 without -D_GNU_SOURCE, because c11 requires
-- to have CLOCK_MONOTOMIC
