Nobody's even commented on my suggestion of using the PCH machinery
to efficiently preload the builtins DECLs from iso90.gch, iso99.gch
or a g++.gch.
I think that the PCH machinery only supports a single monolithic PCH per compile, so such a scheme would preclude, say, a libstdc++ PCH.
That would be a fundamental limitation.  Is this really the case with
the current design?

Yes.

PCH == full memory mmap

If people want to invent a design that covers more cases, automatically, write it up as a detailed design, and put it up some place, maybe on the beginner pages and send us a pointer to it!
