Hello world!

toolchain@ plans to start stabilizing next major gcc version
(gcc-9) in about a week at:
    https://bugs.gentoo.org/698646

Current target is =sys-devel/gcc-9.2.0-r1.

If you think your bug should be absolutely addressed before
that happens please add it as a blocker.

Also feel free to cc toolchain@ explicitly on tricky build failures
without clear path to resolution. We will figure something out together.

gcc-9 had a few known breakages for existing code:
    https://wiki.gentoo.org/wiki/Project:Toolchain#gcc-9
    (also see tracker below)

gcc porting tracker still has 14 unresoved bugs:
