The above is good advice, but I personally don't recall there ever being
a c3 CPUTYPE designation. For example:
$ grep -i c3 /usr/share/mk/bsd.cpu.mk
$ sed q /usr/share/mk/bsd.cpu.mk ; uname -r
# $FreeBSD: src/share/mk/bsd.cpu.mk,v 1.48 2005/05/24 21:24:40 cognet Exp $
6.1-RELEASE
On other hand, from reading your headers:
X-Mailer: Claws Mail 2.8.0 (GTK+ 2.10.11; i386-portbld-freebsd6.2)
suggests to me that it may have been added to 6.2. If that's the case,
then it merits being pointed out.
Cheers.
