:) And I pointed quite a few other issues about enums vs. defines.
According to this one - no one wants to watch enums in debugger.

And, ugh:

(gdb) list
1 enum {
2 A = 1,
3 B = 2,
4 };
5
6 int main()
7 {
8 printf("%x\n", A | B);
9 }
(gdb) bre 8
Breakpoint 1 at 0x4004ac: file ./test.c, line 8.
(gdb) r
Starting program: /tmp/test

Breakpoint 1, main () at ./test.c:8
8 printf("%x\n", A | B);
(gdb) p A
No symbol "A" in current context.

Actually I completely do not care about define or enums, it is really
silly dispute, I just do not want to rewrite bunch of code _again_ and
then _again_ when someone decide that defines are better.
