Hi.  Two files in the source tree have inadvertent trigraphs in them:

src/dist/tcpdump/print-dhcp6.c
src/usr.sbin/pppd/pppd/options.c

In both GCC 2 and GCC 3, -Wall is supposed to turn on trigraph warnings.
GCC 2, however, is completely blind to trigraphs unless -trigraphs is 
also given, somewhat defeating the warning intent.

GCC 3 fixes this mistake, which means warnings on these two files, that 
then trip -Werror.

Any objections to the following patch?

Matt
