Subject: [PATCH] Use ansi stdio extensions when using a mingw compiler

In the C runtime used by mingw compilers (msvcrt.dll) the printf
function does not support the C99 format-width specifier "%ll".

Defining __USE_MINGW_ANSI_STDIO enables mingw's ansi stdio extensions
that implement a C99 compliant printf function.
