           Summary: make-macosx-ub.sh error aborting and directory changing
           Product: Quake 3
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P3
         Component: Misc
        AssignedTo: zakk at icculus.org
        ReportedBy: bugzilla at benmachine.co.uk
         QAContact: quake3-bugzilla at icculus.org


There are a couple of cases in the make-macosx-ub.sh script where an
unrecoverable error does not cause the script to exit, or does not exit as
promptly as it could, causing misleading, redundant, or useless error messages
to be printed.
The patch I am about to attach addresses these issues, and also adds some
attempt to change to the right directory before execution.

I realise it's usually more convenient to open separate bugs for arguably
separate issues, but theses issues are so small individually I felt it wasn't
worth it.
