Right. '-mno-cygwin' is not a supported flag for gcc with version 4.  It was
there to allow a kind of cross compiler that targets Win32 instead of
Cygwin.  This is obviously not what you want anyway so it's of no
consequence to you that the flag has been removed. :-)  There are now
actual cross compilers available in Cygwin for gcc 4 that serve the purpose
of the old '-mno-cygwin' flag.
