All four patches have been applied. Thanks :)
Just a heads up, when you're adding new files to the project, check to
see whether the build system (Makefile.am) needs to be told about these
files. In this case you forgot to add the two test scripts to
Makefile.am. Running 'make distcheck' whenever new files are added
helps catch most of such issues.
Regards,
