20460964 PCRE should have some master test results to compare against
15417417 SUNBT6594265 man page for pcregrep is missing "Last change:" date
Comment out the set -u (nounset) shell option in test-driver,
which errors out when encountering unset variables.
During "gmake test" the pcregrep binary is never called because it
causes a problem in the pcregrep libtool wrapper for
an unset variable $libtool_install_magic.
Problem is not seen when running "gmake check" directly from
command line. Solaris-specific patch not appropriate for upstream.
