From 5924b5736a3bec0c2ef93ddbd1da733745942d59 Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Sun, 27 May 2012 17:48:57 +0000 Subject: Support -Ios='OpenBSD 5.1' to override uname(3) as the source of the default value for the mdoc(7) .Os macro. Needed for man.cgi on the OpenBSD website. Problem with man.cgi first noticed by deraadt@; beck@ and deraadt@ agree with the way to solve the issue.
