Functions are only "jump" labels. Thou you cant expect a program to work
if you cross typecast functions with different argument (or return)

register or stack position. And caller expects return values to be in
right register.

excerpt from a discussion here @

ANSI Classic section 3.3.4, page 47 lines 4 to 5: "A pointer to a
function of one type may be converted to a pointer to a function of another
type and back again; the result shall compare equal to the original
pointer."

Seems to confuse me a lot. I didn't understand the ABC's of the
quoted discussion; nevertheless, this line there in the discussion,
still stings me :(
What does it mean?
First of all, why should be function pointers be typecasted to
something else?
