Author: imp Date: Sun Feb 23 23:36:56 2020 New Revision: 358265 URL: https://svnweb.freebsd.org/changeset/base/358265 Log: Relax machine directives a little. Currently, you can have multiple machine directives if they are otherwise identical. Relax this so that only the machinename part is the same. This allows one to change the machine arch in a different config file you've included easily.
