It is hard for me to think of a good solution for this. The reason
<stddef.h> is not included is because the version of GCC that MSYS ships
with has a bug where it cannot be included multiple times (otherwise it
redefines things many times). But without including it wint_t is never
defined which causes the compiler error...

Maybe doing:

    typedef __WINT_TYPE__ wint_t;

exclusively on MSYS2 would fix it. But that is pretty hacky...
