This is exactly the reason why documenting *FUNCTION on its own is the
wrong thing to do. What we implement in GDB is *EXPRESSION, where
EXPRESSION is an expression in the current language yielding an
address. For C FUNCTION will do as an expression; &FUNCTION will do
as well. Function pointers are a pretty standard feature of the C
language, so I expect users to know about them.
For Ada the appropriate expression is FUNCTION'Address or &FUNCTION.
Other languages might also need a different syntax; I doubt &FUNCTION
will work in Pascal or FORTRAN.
