Re: [armv7 fix] Fix build lang/gcc/4.9

I tried to continue the build of php with the ports snapshot of today and ran into another gcc problem:

Correct, I've spotted this also. I have committed the -Wreserved-user-defined-literal diffs (including the one for
ipa-devirt.c) since they are trivial and we need a working ports-gcc for the upcoming hackathon.

I'm testing the -fbracket-depth=512 diff on arm, build still ongoing.

Well this seems to be handled by the diff in my previous mail, attached
again for convenience. gcc (FLAVOR='no_java no_ada') packages, install,
and seems to run. dpb ongoing.

Technically a clang-specific fix but it already happened with clang-5.0.

OTOH if a single file is affected, -fbracket-depth=n shouldn't have
side-effects on other files...

Yeah, or maybe clang should cope better with such files. Anyway, even
if we can probably remove gcc-4.9 from the dependency chain of a few
more ports on arm, it would be nice to have gcc-4.9 fixed. :)

If your patch is sufficient. If not, please consider using Markus'
patch. ok jca@
