[Piglit] [PATCH] cmake: Enable __USE_MINGW_ANSI_STDIO for MinGW builds.

[Jose Fonseca]

Interesting, I didn't know about __USE_MINGW_ANSI_STDIO.

However, it solves the MinGW problem, but not MSVC --

A more portable solution would be to use inttypes.h PRIdPTR or avoid 
size_t arguments to printf.
