I have the macro:

#define	__sigemptyset(set)	((*(set) = 0L), 0)

Code like:

{
  sigset_t set;
  __sigemptyset (&set);
}

elicits `warning: value computed is not used' from gcc 2.1 with -Wall.
This is annoying.  And, it seems inconsistent.  GCC does not complain the
same code with:

int __sigemptyset (sigset_t *);

instead of the macro.  The return value is computed and ignored in both
cases.
