I'm sorry, but I really don't anything about cross compilers.  I was 
simply passing on the information that (in principle) it should be 
possible to use the new cross compiler instead of 'gcc -mno-cygwin' to 
produce a native windows executable.  Others on the list (Angelo?) might 
be able to give you details.

I can tell you that the cross compiler (for 32-bit windows) is called 
i686-pc-mingw32-gcc.exe and is in the Cygwin package mingw-gcc-core, 
which can be installed by following the instructions in the link I sent 
you.  There's is also a cross compiler for 64-bit windows, which has 
been available for some time now, in the package mingw64-x86_64-gcc-core.

Sorry I can't be of more help.
