There is a missing double quote " in 
8.3 & 9.0 & 9.1RC2 src/etc/sendmail/freebsd.mc
8.2-RELEASE & earlier are OK.

Fix: I append my 
http://berklix.com/~jhs/src/bsd/fixes/FreeBSD/src/gen/etc/sendmail/freebsd.mc.REL=9.0-RELEASE.diff

This patch applies to 8.3-RELEASE and 9.0-RELEASE & 9.1RC3. 
It is not needed for 8.2-RELEASE & earlier.

] understand the difference.  The patch for a fix would befar more trivial :-)

] Why others didnt notice earlier:
]   It's just a comment, I assume not checked by anything automatic at
]   freebsd.org.
] 
] How I caught it:
]   I have my own src/etc/sendmail/ Makefile diffs & fdef'd common.cpp
]   that generates various .mc files for each of my hosts, & many
]   versions, which filters the .cpp to create .mcfiles, inc. a check
]   file that should be an exact match with that version's freebsd.mc
]   ... & cpp complained: unmatched ".
] 
] I will send-pr unless I hear otherwise.
]   But as 9.1-RELEASE is imminent, & it would be a trivial anodyne
]   fix to a comment for re@ , so they want to fix, so cc'd to re@.
] 
] Cheers,
] Julian
