Well, at least it was caught before it was included in an official release. :-)

[Bikeshed: As long as we're making up new names, I'd rather not
intrude on POSIX reserved namespace -- *_t -- not that xcb_* is too
likely to ever collide, so I don't feel all that strongly about it.]

Hmm, not really. 'altenum' is a reference to an otherwise ordinary
enum. There is no way to determine how an enum will be used until it
actually gets used. Some (eg InputFocus) are even used as both an enum
and an altenum.

That's why I suggested a white list of known-to-not-collide enums, for
which a backwards compatible type name could be generated. *_enum_t
for every enum not on that list.

Alternatively, the libxcb generator should know when a name will
collide (since its code generator is not streamy), and could generate
the *_enum_t form whenever it sees a collision.

Does that make sense?
