  Message : Remove system.h. The gyp files already define NOMINMAX and WIN32_LEAN_AND_MEAN. windows.h is also included via the D3D includes. This ends up speeding up the build process significantly by not having windows.h included in nearly every file. Also fixes issues on non-windows systems by not having stdarg.h included in debug.cpp. Change-Id: Id32d9aac37a5a29df832a062dd8024302a798a1c Reviewed-on: https://chromium-review.googlesource.com/183251 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Shannon Woods <shannonwoods@chromium.org> Tested-by: Geoff Lang <geofflang@chromium.org>
