Author: imp Date: Fri Aug 23 16:42:39 2019 New Revision: 351430 URL: https://svnweb.freebsd.org/changeset/base/351430 Log: Turn off -Werror for gcc 4.2.1 for userland As discussed on arch@, gcc 4.2.1 is on its way out. Turn off Werror on gcc versions < 5.0 permantly. This will allow older platforms to continue to compile w/o new errors once we take them out of universe by default. This will also free developers from chasing down obsolete warnings that produce no beneficial changes to the source.
