Under IBM's AIX a pointer to function is the address of three words.
Entry point of function's code.
Address of module's Table of Contents.
Used by some languages' implementations, OCS Ada for one IIRC.
So they went for the `function pointer fits into long' solution to avoid
breakage.
Cheers,
Ralph.
