[PATCH 0/6] [C++] Drop -fpermissive hack, enable -Werror

[Pedro Alves <palves@redhat.com>]

The first 4 patches finally make GDB build cleanly in C++, at least on
x86_64 GNU/Linux and x86_64 mingw.  At this point, I think we should
drop the -fpermissive hack and default to -Werror in C++ mode too,
which is what the last two patches do.

This lets the buildbot catch C++ build regressions promptly -- we
already have a Fedora buildslave building in C++ mode specifically for
that, but it currently misses regressions around pointer casts and
enum conversions exactly due to -fpermissive/-Wno-error.

Other ports still need further C++ conversion work, though the build
failures shouldn't be too many and should be mostly localized to
host/target-specific code.
