[Spice-devel] [PATCH spice] Ensure __STDC_FORMAT_MACROS is always defined first

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

The client/common.h file defines __STDC_FORMAT_MACROS before
including inttypes.h so that the PRI* macros get defined in
C++. This is ignoring the possibility that other global
includes may have already pulled in inttypes.h

We need __STDC_FORMAT_MACROS to be defined before any header
files are included. Putting it in config.h satisfies this,
since config.h is always the first header
