Done. Everything's fine with gtar. As far as the OSF1 'make test' is concerned I've re-run it with gtar, native compiler and SHELL_PATH=<self-compiled-bash>, and everything looks fine except some UTF8 conversion tests which may be caused by some iconv lib issues on this platform.

It indeed is happy with that, this will be very useful to know when working on OSF1 and only having the native tar application.
