My gcc -v  returns:
Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/specs
Configured with: /GCC/gcc-3.3.1-3/configure ........

which is a different version, however my Makefile did work with earlier 
versions
of gcc, so I don't think that the version is the problem. Looking at the 
result of
your gcc -v, I would guess that you are running the MingW tools, not Cygwin.
Perhaps you could try removing the -mno-cygwin from the command line.

Personally I don't see the point of using MingW, using Cygwin with -mno-cygwin
gives one a similar stand alone windows executable.
If you have Cygwin installed, open up a Cygwin bash shell, (not a DOS) shell,
and try the gcc ... command again.
