There is only a YES/set = and > NO/unset. No. There is only set and unset. WITH_option=3D"NO" has the same effect as WITH_option=3D"YES". I think this is confusing and often leads to unintended consequences, but I and also say that some of the WITH_options documented for src.conf (the man page is auto-generated from the code) are either non-functional or broken. I've had some interesting issues with unexpected interactions of WITH_options, as well. Be very careful! --=20 R. Kevin Oberman, Network Engineer - Retired E-mail: kob6558@gmail.com
