1 Comment out the set -u (nounset) shell option in test-driver,

     2 which errors out when encountering unset variables.

     3 During "gmake test" the pcregrep binary is never called because it

     4 causes a problem in the pcregrep libtool wrapper for

     5 an unset variable $libtool_install_magic.

     6 Problem is not seen when running "gmake check" directly from

     7 command line.  Solaris-specific patch not appropriate for upstream.
