+
+Suggested by Richard Purdie <richard.purdie@linuxfoundation.org> in
+<https://lists.gnu.org/archive/html/bug-gperf/2022-07/msg00000.html>.
+
+* autogen.sh: Import also lib/filename.h.
+* Makefile.in (IMPORTED_FILES): Add lib/filename.h.
+* src/options.cc: Include filename.h.
+(Options::print_options): Print only the base name of the program name.
+* tests/*.exp: Update.
