Generally, the more the compiler knows, the better it can do it's job,
so I usually prefer the latter. There are still some places in C (C99
specifically) where you you have no choice but to use macros, like array
declarations. I believe that C++ const variables can be used wherever a
simple #define can.
Actually, the following is valid C99:
const int m = 10;
int
foo(int n) {
char s[n];
char t[m];
...
}
BTW, Is there a reason why mailman isn't configured to set the
reply-to header?
Because we don't want it to. Can we not go there again? Convince
your mailer to set Mail-Followup-To, if you'd like (mutt does that).
