>Organization:
>Environment:
Stock Redhat 7.1 (kernel 2.4.2, glibc 2.2.2), Pentium 200
>Description:
when compiling the following code with -Wswitch,

enum Enum {
  A
};
void f() {
   Enum e;
   switch (e) {}
}

I'd expect to see a warning about as "enumeration value `A' not handled in switch".
>How-To-Repeat:

>Fix:
a quick (and dirty?) solution works for me:
disable default_conversion() in cp/typeck.c for 
ENUMERAL_TYPE. this preserves the ENUMERAL_TYPE and its
possible values until 
stmt.c:check_for_full_enumeration_handling()
which is called from stmt.c:expand_end_case().
