1298466 - silence spammy warnings from clang-cl when compiling icu

Status: RESOLVED FIXED

Description

[Nathan Froyd [:froydnj]]

We get two warnings for ever ICU source file we compile:

- ICU defines WIN32_LEAN_AND_MEAN, which we do as well (in mozilla-config.h), so we get warnings about redefined macros;
- We get warnings from clang-cl about "Microsoft include rules", which AFAICT are more or less the include rules everybody expects

We should just turn these off.

Bug 1298466 - avoid some spammy warnings for ICU when compiling with clang-cl; .mielczarek

We don't need to hear about ICU redefining macros we set up or about
include paths that are Microsoft-specific, but still resolve to where
they need to go.
