Subject: scons: Adjust the warnings for VS.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=42b9f8590d3002bc04b08397031b80e4a4d6e921;p=mesa.git

scons: Adjust the warnings for VS.

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.
