The macros on Cygwin don't use any knowledge about Cygwin runtime
internals. They use knowledge about how gmalloc and unexec work on
Cygwin. Prior to dumping, gmalloc uses a version of sbrk defined in
sheap.c, which allocates space in the static heap (also defined in
sheap.c). But the question still remains about what to do on other
platforms.
