Yeah.

This is ok, please check it in.

If/when something like this goes in, would rather rename stdc++.h to
whatever is standardized, and then build on it with std-checked just
defining _GLIBCXX_DEBUG and including stdc++.h. h

That is what extc++ should be. If things are missing add them please.

Of course.

My own feeling is that the single header, stl.h or stdc++.h or however
it is spelled, is useful and makes sense to standardize. (If only to to
provide an abstract interface to precompiled headers as is the
libstdc++ usage.)

I don't really see much use for other ones.
