>Description:
Given a Makefile with three OPTIONS

OPTIONS_DEFINE=         AUTHN_DBD DBD SESSION_DBD
OPTIONS_DEFAULT=        AUTHN_DBD DBD

The value of DBD is unexpected with bsdgrep but fine with the old GNU grep 


>How-To-Repeat:
For testing I've created a simple test port.
 http://people.freebsd.org/~ohauer/diffs/PR_181717/Makefile

> grep --v
grep (GNU grep) 2.5.1-FreeBSD

> make config (switch AUTHN_DBD and DBD to ON)
> make showconfig 
===> The following configuration options are available for pr181717-1.0:
     AUTHN_DBD=on
     DBD=on
     SESSION_DBD=off
===> Use 'make config' to modify these settings


> grep --v
grep (BSD grep) 2.5.1-FreeBSD

> make config (switch AUTHN_DBD and DBD to ON)
> make showconfig
===> The following configuration options are available for pr181717-1.0:
     AUTHN_DBD=on
     DBD=off      <-- unexpected
     SESSION_DBD=off
===> Use 'make config' to modify these settings


>Fix:
Switch back to GNU grep
