Description of problem:

I just tried to compile package expect-5.42.1-1 from 
Redhat Fedora Core 3.

The compiler said

1.

expect.c(2018): warning #1011: missing return statement at end of
non-void function "exp_tcl2_returnvalue"

What happens if parameter x is not one of the values listed in the
switch statement ? Rubbish is returned to the caller.

Suggest add return statement at the end of the routine which does
something sensible in the case of bad data.

2.

expect.c(2034): warning #1011: missing return statement at end of
non-void function "exp_2tcl_returnvalue"

Duplicate.
