But having it in the .h file may come in handy if we want to split the overlong mingw.c into several compilation units...

Now you're mixing all three variants...note that with my suggestion to #define crt_foo in mingw.h, you don't need '#undef foo', nor redefine foo (your variant), nor rename other callers in mingw.c to 'mingw_foo' (Hannes' variant).

Callers of foo() would simply write "foo()", no matter whether in mingw.c or anywhere else. In the special case that you really want the CRT version, you'd write crt_foo(). This works everywhere, even in core-git code wrapped in #ifdef GIT_WINDOWS_NATIVE.
