I think for the above to be a function, hab and hframe would
have to be the names of types, which they aren't. Also,
although I'm not sure, I think that there is enough context to
disambiguate---a function declaration cannot be followed by a
point (but I'm not sure whether look-ahead has to be considered,
and if so, how much).

FWIW: his code compiles for me (g++ 4.2.1 under Linux). His
error messages also seem to suggest that his compiler is also
treating MenuShowAccel as a function in the line in question.
In fact, it looks like the compiler is treating
WinQueryAccelTable as a macro which expands to its arguments
here, but if that were the case, the previous declaration would
not compile.

I don't think so. It shouldn't, and that doesn't correspond to
the error messages he posted either.
