I feel a bit strongly the other way: POSIX is using an
long-established convention of ending type names with _t,
that seems to me useful to programmers for keeping track of
what's going on.  As you say, the xcb_ on the front should
be sufficient to keep us out of the POSIX namespace.

This last is what I was trying to suggest, actually.  AFAIK
there will only be a collision for names that have at least
one altenum form use?
