It is intentional so that it could share third party extensions

It's checked by configure.

	AC_CACHE_CHECK(for mingw32 runtime DLL, rb_cv_msvcrt, [
	AC_TRY_LINK([#include <stdio.h>],
		    [FILE* volatile f = stdin; return 0;],

		    [rb_cv_msvcrt=msvcrt])
	test "$rb_cv_msvcrt" = "" && rb_cv_msvcrt=msvcrt])
