[libvirt] [PATCH] Define __USE_MINGW_ANSI_STDIO in config.h
From: "Daniel P. Berrange" <berrange(a)redhat.com>
Latest mingw64 can provide *printf functions which
support GNU format specifiers. It won't do that unless
you have defined __USE_MINGW_ANSI_STDIO though.
GNULIB's 'asprintf' module detected that mingw had
the asprintf function, but didn't define the
__USE_MINGW_ANSI_STDIO so we got left with the version
offering Win32 format specifiers, instead of GNU formats.
It could perhaps be argued that gnulib's 'asprintf'
could be defining __USE_MINGW_ANSI_STDIO for us ?
