>Description:
The latest changes to pkgsrc introduce a PREFER_PKGSRC variable
that is checked with the empty() macro. Since the variable is
nowhere defined by default the Makefiles break with a syntax error.

-current has a more tolerant make that accepts undefined variables
in the empty() test since:

date: 2003/09/06 06:52:08;  author: sjg;  state: Exp;  lines: +4 -4
Make empty() consider an undefined variable as empty,
rather than throw a syntax error.

but 1.6.1++ has not.

>How-To-Repeat:
Try to build a package that relies on PREFER_PKGSRC.

>Fix:
As a workaround 'setenv PREFER_PKGSRC no' or initialize the variable
in mk.conf.

As a fix, pull up the changes in cond.c to the 1.6 branch.
