Subject: CVS commit: xsrc

Module Name:	xsrc
Committed By:	tron

Modified Files:
	xsrc/xc/config/cf: NetBSD.cf
Log Message:
Use only "-O" on m68k because at least "libX11" will not be completely
functional otherwise.


If or when I get my system to build world again, I'll see about putting
out another X snapshot. You are of course free to compile the xsrc
yourself and see if your problem goes away in -current.

Later.
