This is not a particularly critical problem, but I couldn't resist the
opportunity to show off our optimizing compiler :-). Building a2p with the
optimizer turned on gives the following message:

	cc -c -O3 -g  a2p.c
"a2py.c", line 1210: warning: Uninitialized item <numargs> detected

Looking in a2py.c shows the error in function fixfargs. The call to fatal
uses an uninitialized variable in the error message, perhaps it should be
prevargs?

fixfargs(name,arg,prevargs)
int name;
int arg;
int prevargs;
{
    ...
    if (type == OCOMMA) {
	numargs = fixfargs(name,ops[arg+1].ival,prevargs);
	...
    }
    else if (type == OVAR) {
	...
	numargs = prevargs + 1;
    }
    else
	fatal("panic: unknown argument type %d, arg %d, line %d\n",
	  type,numargs+1,line);
               ^^^^^^^
    return numargs;
}
