The choice of C compiler should not make a difference, and GCC is a good C compiler. However, it may be best practice to use a compiler designed for Microsoft. It does seem that in the past there were many C compilers out there that did a good job when Windows was only 32 bit, though some 16-bit programs were still around. Borland had a working C compiler, but I have heard they have dropped out of the market with 64-bit Windows becoming commonplace and Visual Studio being available for free and much improved.

I also believe that programmers write sources and scripts with the assumption that Visual Studio will be used for Microsoft Windows, GCC will be used *nix programs, and XTools will be used for Apple programs that will use Apple libraries. One cannot simply write generic source code for a program and expect the build tools to compile the program without instructions.

Keeping this in mind, I would not expect GCC to build perfectly for Windows any more than Visual Studio to build perfectly for Linux. I know I can pass parameters on the command line in Linux to use specific tools. However, I have little experience in doing this in Windows. Perhaps, I should simply change the environment variables to hide undesirable tools, reboot and compile. 

In conclusion it seems that the answer is to pass parameters or hide GCC.
