[Bug gdb/11067] New: p <enum constant> should print the constant's value

$ cat test.c
enum E {
Val1,
Val2
};
int main() {
    enum E e = Val1;
    return e;
}

...
Temporary breakpoint 1, main () at test.c:6
6           enum E e = Val1;
(gdb) n
7           return e;
(gdb) p e
$1 = Val1
(gdb) p Val1
$2 = Val1
(gdb) p (int)Val1
$3 = 0


When I print a variable, printing the symbolic name for its value is right, but 
when I print the symbolic name, gdb should print its numeric value instead (or 
in addition).

There's an easy workaround, of course, but gdb should DTRT in the first place.

Lacking any consensus on the utility, implementation, or display format for this
enhancement, and the evolving mutually exclusive requirements, there's no way to
make this enhancement work.

Thanks, Chris, for your work on this. I guess such a simple change was just asking 
to be bikeshedded into oblivion.

Or use the fact that the expression defaults to $.

(gdb) p Val1
$1 = Val1
(gdb) p/d
$2 = 0

Or:

 (gdb) p Val1+0

Which I find even easier to type, as what I actually usually do is:

 (gdb) p Val1
 $1 = Val1
 <up>+0<enter>
 $2 = 0

You can also use "p /d" as a work around. It is less typing than "p (int)"

(gdb) p /d Val1
$4 = 0
