No.  GNU/Linux and Windows have entirely different, incompatible
runtime environments, you can't just say "I want this to run on
Windows" and expect a GNU/Linux compiler to link to the Windows
runtime.  You'd need a cross-compiler targeting Windows, as described
at rmathew's document that you've been posting, which would need
copies of all the Windows runtime files (i.e. the binaries for
"mingw-runtime" and "w32api")

Assuming you're talking about x86, it's -m32, as documented in the GCC manual.

Maybe it would be easier to just run normal Java code on Windows,
instead of compiling to native code with gcj.
