Yes, this is on Linux; a slightly modified version of Slackware.

Actually, there is no manpath binary on my system, nor manual page for
it.

Alright! :-)

Because for a second I thought I was hallucinating (again.. :P), 'cause
I've compile the 1_13_1 tag and the problem was not there, then checked
with the 1.13.1 release tarball, and it was not there either, I dug
deeper and turns out, that with these latest tests, I didn't use my
usual CFLAGS during the compilation. And the culprit for me seems to be:
$ cvs up -rVERSION_1_13_1
$ CFLAGS='-DOSNAME=\"Slackware\ Linux\"' make
...
$ ./mandoc -Tlint test.1
mandoc: ../mdocml/test.1:1:2: WARNING: cannot parse date, using it verbatim: August 27, 2014

Without the -DOSNAME define, it doesn't emit this warning. I know I'm
not crazy! Sort of... :)

Sorry for not posting the exact steps I've been using to compile
mdocml... rookie mistake..

But regarding CVS HEAD, even with the OSNAME define, it won't tell me
that warning.
