That only applies to DMD's (which only supports Linux anyway) Phobos,
but not to GDC - it uses autoconf to generate those gPhobos constants.

For instance, on Mac OS X we have:
#define        O_CREAT         0x0200

Take a look at the programs in d/phobos/config, for all the details.
You need to create the frag-gen, frag-math and frag-unix configs...
