Thanks Koehne Kai, your explanation really clear things up. I will follow your methodology, and when the time comes, I will switch to MinGW-64 compiler. So, for now, MinGW-32 is good enough. Have a wonderful day!!

Just to get this straight: - "cross compiling" in this context means that you're using a 32 bit toolchain to generate a 64 bit binary, or the other way round. - You can deploy 32 bit binaries on 64 bit Windows 7 / 8. This is done by an emulation layer called WoW (Windows on Windows), but really works without any hassles. Just check out "C:\Program Files (x86)", all apps here should be 32 bit ! It doesn't work the other way round though, 64 bit binaries can't run on a 32 bit Windows. - That said, there are of course applications that benefit from using 64 bit (e.g. using a lot of memory, kernel tools etc...) > Please, could you tell me which MinGW-64 flavour I should download in > order to this? I'd personally avoid the cross-compiler hassle, and use a native 32 bit toolchain. If you then decide you really want a 64 bit binary, just install a 64 bit toolchain alongside and recompile your project ... That said, at least TDM-GCC supports generating too.
