Archie Cobbs once stated:

=Brings up a related question I was wondering about.. what happens if
=you compile the kernel -O2? I guess it must break something, otherwise
=that would be the default.. ?

My current kernel is compiled with:

	-O2 -fomit-frame-pointer -fexpensive-optimizations -mno-486 \
		-mpentium -malign-jumps=0 -malign-loops=0

using the gcc-2.8.1 compiler. I had to add the libkern's muldi3 (I
think), to the Makefile manually.

Previously, I was using the cc with similar:

	-O2 -fomit-frame-pointer -fexpensive-optimizations -mno-486 \
		-malign-jumps=0 -malign-loops=0

The system is quite stable: "up 6 days", with two concurrent xsessions
(local and remote), Netscape, builds, ccd, softupdates, whatnot.

Load reaches 4-6 sometimes...
