i built the cross-compiler by my own, but would be pleased if there are
any cross-compilers publically available!

here the gcc versions i use:

[raho AT pcraho linux]$ gcc --version
gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

[raho AT pcraho linux]$ /opt/cygwin-cross-gcc/i686-pc-cygwin/bin/gcc --version
gcc (GCC) 3.2.3

[raho AT pcraho linux]$ /opt/cygwin-cross-gcc/bin/i686-pc-cygwin-gcc --version
i686-pc-cygwin-gcc (GCC) 3.2.3

[raho AT cygwin cygwin]$ gcc --version
gcc (GCC_ 3.3.3 (cygwin special)
