Yes, but makewhatis(8) used to parse only the NAME section of the man
pages. The new tools, parse almost the complete man page. The NAME
section is the key here, if the name of the man page and its one line
short description (.Nd) cannot be extracted from the man page then the
rest of the data from that man page is useless because in the database
we can't possibly identify which man page does this data belong to, so
the tool simply reports an error for such pages. However, for rest of
the sections, it tries to be as lenient as it can be (and in normal
cases it should not report errors).
However man(7) pages are a bit tricky to parse properly, it is
possible that there might be some man pages out there with NAME
section in a form that makemandb does not expect.
