And one more problem only for mingw triple.  I redefine printf 
inside my module, and only import core.stdc.stdio : FILE, BUFSIZ, 
EOF, FOPEN_MAX, FILENAME_MAX, TMP_MAX;

linux & osx work well, on mingw:

Error: function my.stdio.printf at /d/src/my/stdio.d(206) 
conflicts with function core.stdc.stdio.printf at 
/usr/local/bin/../import/core/stdc/stdio.d(1309)
