If we rework it to work under GCC _we_ use it and can therefore make sure
the stock code is ok.  Otherwise you rely on run-time checking.  It would
depend on the amount of reworking really.  For the simple case of the
format checking itself, we just pull the trick where:

#ifndef __GNUC__
#define __attribute__(x) /* Nothing */

void   send_to_charf(struct char_data *ch, const char *messg, ...)
       __attribute__ ((format (printf, 2, 3)));

Other compilers should have that feature anyway, maybe they will later.
