-# Mingw-w64 trunk (jan 27 2012) contains an inline implementation of the
-# vscanf and vfscanf functions in stdio.h. This break compilation of gnulib
-# which tries to provide its own implementation for the vscanf and vfscanf
-# functions. Workaround is by making sure that the inline implementation
-# isn't triggered by #include <stdio.h>
