I think I found the problem.

In my initial mail of this thread, I reported, that after upgrading
Freebsd 11.0-CURRENT to r290538 (including locale and localedef updates)
I am not able to build lang/gccXX any more. All I get are errors like
that in usr/ports/lang/gccXX/work/build/gcc:

----
In file included from .././../gcc-4.8.5/gcc/genflags.c:26:
In file included from ./tm.h:16:
./options.h:4293:3: error: redefinition of enumerator 'OPT_C'
  OPT_C = 129,                               /* -C */
  ^
----

After more than 20 of them the build stops with
fatal error: too many errors emitted, stopping now [-ferror-limit=]
20 errors generated.


This is with locale for Germany:
LANG=de_DE.UTF-8
LC_CTYPE="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_MONETARY="de_DE.UTF-8"
LC_MESSAGES="de_DE.UTF-8"
LC_ALL=


If I use 'LC_COLLATE="C"' for the build, the build works fine again:

cd /usr/ports/lang/gcc48
env LC_COLLATE="C" make
...


So it seems, that something with the new 'locale' code in base of HEAD
is not working as expected here? (At least for other locales than US?)

I added bapt@, because he is the author introducing the new code into HEAD.

Hope, my explanations are clear enough to get the problem. Please feel
free to ask for more information, if needed.
