+       Rework defective assignment of product version resources.
+
+       * Makefile.in (BUILD_TAG): Avoid creating an empty build.tag file.
+       (PACKAGE_VERINFO_SCRIPT): Ensure that the build tag is generated as a
+       string of non-zero length.  Do not assume that it comprises only two
+       elements; extract the final two, as the third and fourth elements
+       of the product version meta-data record.
