[PATCH 04/14] Set _O_BINARY as default fmode for both MinGW and MSVC

[Marius Storm-Olsen <mstormo@gmail.com>]

MinGW set the _CRT_fmode to set both the default fmode and
_O_BINARY on stdin/stdout/stderr. Rather use the main()
define in mingw.h to set this for both MinGW and MSVC.

This will ensure that a MinGW and MSVC build will handle
input and output identically.
