[Mesa-dev] [PATCH 2/9] scons: Adjust the warnings for VS.

[jfonseca at vmware.com]

From: José Fonseca <jfonseca at vmware.com>

Silence insignificant warnings so significant warnings have a chance to
stand out.

The only abundant warning that's not silenced here is "C4018:
signed/unsigned mismatch", as it could hide security issues, so it's better
to actually fix the code.
