I've just committed a patch to cc-mode.el and cc-engine.el which fixes
Simon's (first) bug.  [The "variant" he mentioned is a distinct bug.]

It's a fairly scrappy ad-hoc patch - it fixes a particular simple bug
scenario which will surely occur frequently.  Its idea is to remove
tokens from the cache `c-found-types' whenever these tokens are broken
up (e.g. by typing stuff in the middle of them, or removing space which
separated them from other tokens) or when their syntactic identity as
types ceases is disrupted.

I think this cache mechanism should to be thought through and either
abolished or amended to work consistently.
