Bump for my parent message, that I'm very surprised at the lack of
responses to two messages in this thread.

ACK on both patches.

[gentoo-dev] [PATCH 2/2] meson.eclass: disable werror

[Sam James]

It's Gentoo policy to disable Werror where possible and this is
a builtin Meson option, so let's use it, to save needing to
add this all the time in ebuilds.

[gentoo-dev] [PATCH 1/2] meson.eclass: disable PCH

[Sam James]

It's already masked and disabled in GCC and it causes a huge
number of problems, but we need t odo this to avoid automagically
trying to use PCH-even-once-it's-been-disabled-in-the-compiler.
