The _XOPEN_SOURCE 600 can go; POSIX 200112 is enough.
The _GNU_SOURCE is needed for mremap.

Ideally, I would move heapRemap out of gc.c and into platform/mremap.c.
Then you don't need the _GNU_SOURCE in gc.c; only in linux.c and cygwin.c
where it makes the most sense anyways---platform dependant.
One less macro to manage that way too.
