Yes, but there will be other headers available under the synthetic target than
under the real target, so I'll have a different environment and won't be
able to check whether my software will work without CYGPKG_LIBC_STDLIB (which
my application might not need). I think the functions for accessing resources
from the host under the synthetic target should be independent from the
actual configuration for the target.

Why should I reverse engineer it if is available under a BSD license ?
Anyway, since I now know the code, I can't reverse engineer it anymore.
