switch() difficulties in gcc v1.35

[weisen at eniac.seas.upenn.edu]

Thanks to all those who gave me (non-obnoxious) replies to my posting.
I didn't realize that gcc would interpret `defualt' in a case xxx: as
a label if it hadn't been defined.  Is this non-ANSI C not to give an
error for undefined and un-prototyped symbols.
