If a va_list is passed across the boundary between libraries. then they
both have to use the "old" ABI, or else they both have to use the "new"
ABI.

Yeah, irritating. We certainly don't want to make ABI changes often. If
anyone sees a case that the new ABI can't handle, please say so REAL SOON.

A quick grep through /usr/include shows va_list mentioned in assorted I/O
things, curses.h, gtk/gtkarg.h, tcl.h, linux/kernel.h (vsprintf),..

On the good side, testing should catch any bugs introduced this way.
There isn't any subtlety about the differences.

I'm open to suggestions about where to document this.
