Earnie has already beaten me to it, in recommending _WIN32 as a better 
macro choice, but just to consolidate:--

- Use `#ifdef _WIN32' to guard code which is generic for native Win32 
API, irrespective of the compiler in use.

- Use `#ifdef _MSC_VER' *only* if the guarded code absolutely *must* be 
compiled using a Microsnot compiler.  In this case, you should provide 
fallback code for other compilers, so you really should have a *very* 
compelling reason to provide the _MSC_VER specific code at all; in the 
majority of cases, you might just as well use the generic _WIN32 code 
without any need for the _MSC_VER specific alternative.

- Use `#ifdef __MINGW32__' only for code which explicitly requires the 
MinGW 32-bit compiler; again, instances of this should be rare, in 
comparison with instances where _WIN32 would be the more appropriate.
