Does that mean that I can now remove the --disable-werror from my daily C++
bootstrap run ?
Well, that certainly worked, as exemplified by this:
http://gcc.gnu.org/ml/gcc-testresults/2011-05/msg01890.html
At least that would enable my daily run (between 18:10 and 20:10 UTC) to
catch -Werror mistakes ...
It's great that some people understand the intricacies of the
infight^H^H^H^H^H^H differences between the C and C++ type model.
OK: 1/2 :-)
I suspect this infight would vanish if we just switched, as we discussed
in the past.
Perhaps it would just help if we implemented the next step of the plan
(http://gcc.gnu.org/wiki/gcc-in-cxx):
# it would be a good thing to try forcing the C++ host compiler
requirement for GCC 4.[7] with just building stage1 with C++ and
stage2/3 with the stage1 C compiler. --disable-build-with-cxx would be a
workaround for a missing C++ host compiler.
Of course, that still wouldn't make it possible to implement C++
solutions for C hacks because the --disable-build-with-cxx crowd would
cry foul over this ...

Or the other way around, build stage1 with the host C compiler, add
C++ to stage1-languages and build stage2/3 with the stageN C++ compiler.
That avoids the host C++ compiler requirement for now and excercises
the libstdc++ linking issues.
But yes, somebody has to go forward to implement either (or both) variants.
Not that I'm too excited to see GCC built with a C++ compiler (or even C++
features being used).
