ah you are right !   to be honest, I'm not 100% sure what's happening here, let me look.  me feeling is that it's something particular to codeblocks or msys....  I'm not 100% sure how .rc files get implemented, I know msys has some weirdness with slashes because of the masking of windows to unix file paths, maybe this is related?  I'll dig into it.   for sure it's working on CB...
