Another comment:  I don't believe the C spec provides any definition for what
a pointer to a function IS; it just says you can use it to CALL the function.
It need NOT point to the function's code.  In fact, the C compiler that Apollo
sells has function pointers pointing to "function blocks" that indirectly
point to the function - needed because of cross-mapping-segment calls, or
something like that.
