From 15c5595bb144d8018ebd922c6914772958cbf2b2 Mon Sep 17 00:00:00 2001 From: Jose Fonseca Date: Fri, 20 Mar 2015 06:53:09 +0000 Subject: scons: Ensure inttypes.h is always pre-included on MSVC. It's a bit hackish couldn't find another solution. See code comment for details. The warning is useful, so universally disabling doesn't sound a good idea.
