It's not "roughly the same". _GNU_SOURCE makes some symbols visible that are
not visible by default. Whereas _DARWIN_C_SOURCE makes some symbols visible
that are already visible by default but hidden when _POSIX_C_SOURCE is defined.

The usual idiom in the MacOS X header files is

  #if !defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE)

So, I expect that your change will be a no-op for almost everyone.
