One other clangism is that clang warns about compiling a .c file in

It wants an explicit '-x c++' to force the language mode. However,

I think you could add it in its own variable:
FORCE_LANG_FLAG = -x c++
and add that to INTERNAL_CFLAGS.
I assume a massive .c -> .cc
(or .cxx, etc.) rename is not in the roadmap (it would presumably be
very
disruptive to pending patchsets)?
I think it will have to be done at some point... it will be a bit weird
and counter intuitive for newcomers to see .c files containing C++.
That, and analysis tools that select the language based on the
extension. For example, I use Eclipse CDT for my development, and it
assumes C code for .c files by default. I can go change some obscure
setting to force it to consider it as C++, but it would be nicer for
everybody if we didn't have to do that. Actually, I just checked and
it's the same with vim and emacs. If we want to do it right, we would
have to rename .h into .hpp or .hh as well. And it would be as painful
to do it in 5 years as it would be to do it now, so I don't see why we
would wait...
About the merging of pending patches: if I try to apply a patch
including a change to a file that was renamed with "git am", it fails.
But if with "git rebase", git seems to handle it correctly. So there's
hope.
