Subject: Re: [PATCH 4/5] create 32-/64-bit generic bits overlays
Before committing this I'd like to consider whether it might make more
sense to remove even more. By having the arch's alltypes.h.in define
one or more simple internal-use macros for word-size, I think most/all
of these definitions could go in the top-level headers directly,
letting us actually remove entire files (posix.h, limits.h, stdint.h,
maybe others) from bits.
One thing I'd particularly like to do is get the duplicate pthread
type definitions out of the individual archs' alltypes.h.in files and
into the generic alltypes.h.in, so that there's no risk of introducing
inconsistency when new archs are added. This could be done with such a
macro, but it could also be done with an approach like what you have
now, using multiple bits fallback dirs to produce alltypes.h.
