MinGW handles CRT linking implicitly. If using ANSI stdio, it will link 
against its own CRT library (libmingwex) which provides ANSI-compatible 
versions of printf functions, and then link against msvcrt to resolve 
everything else.

You can see this in practice if you disassemble our crosstests—before 
this change, they don't link against "printf" from msvcrt, after this 
change they do.
