[dwm] Compiling with pcc

So OpenBSD not so recently imported pcc into their tree. I myself
recently compiled it and tried to compile dwm with it. I was able to
compile dwm successfully but receive 4 warnings related to
XSetErrorHandler. I realize this compiler is still in development and
these warning issues might not be dwm's fault but rather a bug in the
compiler, but I thought I'd post something and see if anyone might have
any suggestions where I might look to fix whatever is causing the
warnings. Thanks.
