Reread the thread. I indicated you should have those symlinks. It *may
work* without them, that is different from what *I would do*.

gcc -mno-cygwin isn't a cross compile. It links with a different libc,
and puts different headers in the search path - that's all. It *also*
happens to meet the criteria for a cross compile in that
1) cygwin gcc accepts / and \ paths
2) the mingw libraries are present and the file format is understood.
3) The resulting binaries are compatible with the platform.
This is more of an accident than plan :}
