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/

$ sed q /usr/share/mk/ ; uname -r
# $FreeBSD: src/share/mk/,v 1.48 2005/05/24 21:24:40 cognet Exp $

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.
