All right, all right! Everybody chill out. :-) So writing even
a short code at one in the morning is not the best time for me. :-)
A trivial to repair by a single cast. "return (c1 - c2)" happens
to do a right thing because of a type of the function but I confess
that I was not thinking in these terms.
If you will re-read the context you may discover that I was responding
mostly to a comment about "cool gotos" which did not look to me cool at
all (not because of their presence, but because of a resulting tangle).
Whatever.... Computing return values was truly secondary here even if
I agree that it should be done right. :-)
Interesting that nobody commented on curious effects of passing 'len = -1'
as an argument to the original; especially if you are comparing something
not null-terminated. Not an intended usage, but accidents do happen.
