I'll update to 11.0 -r300904 to pick up the external toolchain fix for
-r300886's problem.

The above likely would have problems with finding files in /usr/local/include
when devel/powerpc64-gcc is in use and various ports have been built. If you
use -v for the gcc based compiles the search list will show /usr/local/include
in the list the way that devel/powerpc64-gcc is normally built. In my context
there are some files from ports there that would conflict with some system
headers.
Bryan Drewery is having me do experiments with building gcc with
--with-local-prefix assigned to avoid this. (I started these experiments after
my last report to you.) Before this I was using C_INCLUDE_PAPTH and
CPLUS_INCLUDE_PATH to have /usr/include and /usr/include/c++/v1 searched before
/usr/local/include based paths.
Actually so far I'm only doing the experiment with devel/powerpc64-gcc (used as
the so-called "cross compiler" in my self-hosted context), not with the
lang/gcc49 that I use as the system compiler: for lang/gcc49 I'm still using
C_INCLUDE_PAPTH and CPLUS_INCLUDE_PATH to avoid /usr/local/include based paths
from finding files. In part this is because I expect port building problems if
I use lang/gcc49 to build ports without lang/gcc49 having /usr/local/include
implicitly. I do not use devel/powerpc64-gcc to build ports.
As stands I will next be trying building devel/powerpc64-gcc based on:
--with-local-prefix=${LOCALBASE}/lib/gcc/${GCC_TARGET}/${PORTVERSION}
which should make the search list entry (when it tacks on /include) a redundant
one with the one that follows what would otherwise be /usr/local/include in the
list. Using --with-local-prefix=/usr still resulted in /usr/local/include being
in the search list. No surprise given that
https://gcc.gnu.org/install/configure.html says:

It looks like they have code to detect the attempt to use /usr and prevent it.
