Compile fix for MSVC: Do not include sys/resources.h
Compile fix for MSVC: Do not include sys/resources.h

Do not include header files when compiling with MSVC that do not
exist and which are also not included when compiling with MINGW.
A direct consequence is that git can be compiled again with MSVC
because the missing "sys/resources.h" is no longer included.

Instead of current

	#ifndef mingw32 is the only one that is strange
        ... everything for systems that is not strange ...
        #else
        ... include mingw specific tweaks ...
        #endif
        #ifdef msvc is also strange
        ... include msvc specific tweaks ...
        #endif

it turns things around and says what it wants to achieve in a more direct
way, i.e.

	#if mingw32
        #include "compat/mingw.h"
	#elif msvc
        #include "compat/msvc.h"
	#else
        ... all the others ...
	#endif

which makes it a lot simpler.
