In MSYS you compile wxWidgets with the automake build system and obtain 
a wx-config binary. So the above fix would not work for MSYS. MSYS has 
access to a usual wxWidgets installation, but not via C:/wx... - the 
drives are accessed by /c/wxWidgets-2.4.8. But according to the 
installations instructions of wxWidgets for MSYS, where the usual 
configure/make process is recommended I would stick in the MSYS case to 
the unix find_style.

That I'm not sure. And it wouldn't make too much sense, since MSYS is by 
definition the minimal system to use the unix configure system. If the 
user doesn't want that, he should use the Windows CLI (pure MinGW), 
since he doesn't use the capabilities of MSYS anyway.

Thanks for the patch,
Werner
