May th= is > also be the case for FreeBSD? That's ironic, considering that a while back they were adamant that if the suffix wasn't in the list cited in POSIX, then it was a bug in the makefile. Your example does not list a suffix for ".1". It would be harmless to update groff's makefile to provide that, and a corresponding suffix-rule. --=20 Thomas E.
