Re: RFA: abstract C++ ABI dependencies

Thanks for reading so carefully (and promptly!).  I thought I'd been
careful, but clearly there's a bunch of stuff botched.  I'll post a
revision in a bit.

I've answered your questions below.

I share your preference.  In the next rev of this patch, cp-abi.h will
no longer #include any other files.

Because they use functions which used to be declared elsewhere, but
are now declared in cp-abi.h.  I've clarified the ChangeLog entry.
