Replaces `undefined' code with `defined' behavior...
gcc 2.96 performs switch cases range analysis, warns about unreachable
cases, and weeds them out.

VALUE is first coerced into the type of i. If i is signed, VALUE is
unsigned and exceeds i range, you lose... the result of the conversion
is undefined.
