With the cvs checkout, mandoc(1) accepts the given date for me too.

TBH, I'm a bit confused. You see, I've used 1.12.3 before, and I've just
upgraded to 1.13.1 recently. And because 1.12.3 did not have a
./configure script, furthermore with 1.13.1 I was not supposed to run
./configure directly, it seems to me, something has changed throughout
the development that it seems has been fixed in HEAD, but exists (for
me) in 1.13.1.
Does this make sense?
