To be honest, I do not know what libPW.a is, but a little poking around and
disassebly turned up a few things:

"libPW.a" defines its own version of 'rename', which seems to do basically
the same thing as the regular 'rename'.  One difference is that some of the
internal libPW.a routines called by 'rename' use a string variable called
"Error" to construct error messages, as in

	if (link(p1,p2))
	{
		sprintf(Error,"can't link `(%s)' to `(%s)' (%d)",p2,p1,0x70);
		fatal(Error);
	}

Error does not seem to be defined anywhere in libPW.a; but if this is your
only problem with libPW, you could try declaring

char Error[80];

somewhere in your program.
