"Wastes an int"???  - nformal is on the stack anyway, so if you use
"register" before the '{' the compiler copies it to a register.
Therefore the code above is IDENTICAL in effect - but leaves the
ORDER of "register" assignments up to the programmer.

I support the K&R method of the compiler following the programmer's
order until registers are used up.  After all, C is supposed to give
the programmer as much control of the machine as possible.
