cvslatest vs. local changes

[Paul Goyette <paul%whooppee.com@localhost>]

Any clue on how to make ``build.sh -P'' work when you have local
changes in the source tree, and those changes have been merged
with subsequent real changes via ``cvs update''?

I'm getting

	nbcvslatest: Malformed time `Result of merge' in `/build/netbsd-local/src_ro/distrib/sets/lists/debug/CVS/Entries'

There are indeed several changed files in my local tree which have
the `Result of merge' value in the date field.

The cvslatest(1) utility has a ``-i'' switch to ignore malformed
time-stamps, but there doesn't seem to be any way for build.sh to
specify it.

Since the `Result of merge' seems to be a valid value, perhaps we
should either just ignore it, or stat(1) the relevant source file
and use its last-modified date?
