Doesn't seem to be too bad. I managed to compile the recompiler with VS 2005. Will test soon if there are any runtime issues.

Maybe easier will be to use MinGW64. Cross compilation process is just a compilation with cross-compiler :) - you build GCC as Windows executable capable to produce Linux binaries. There are docs on the net. GCC version is around 3.4, IIRC. Thanks, Nikolay.
