But as I said, you don't want to set the when compiling world and kernel anyway ;). I usually have two sets of CFLAGS and CXXFLAGS in my make.conf, one which I use when compiling world/kernel and one which I use for everything else. It's just a matter of moving two '#' when switching, the lazy could even write a script =). > > On Thu, 09 Jan 2003 11:22:39 -0800 > Joe Laughlin wrote: > > > In the UPDATING file, the following is noted: > > > > FreeBSD 5.0-CURRENT has many debugging features turned on, in > > both the kernel and userland.
