So what is the right way to handle these rules?  Should emacsapp be
changed to point to ${srcdir}../mac/Emacs.app?  If yes I'll check in this
patch:

2002-06-18  Andreas Schwab  <address@hidden>

        * Makefile.in (emacsapp): Prepend ${srcdir}.
        (${emacsapp}Contents/MacOS/Emacs): Support building outside source
        directory.
        (${emacsapp}Contents/Resources/Emacs.rsrc): Likewise.

Thanks, that works.  But Emacs should not simply abort just because
GetNewCWindow failed.  Instead it should print an error message and exit,
since that is not an internal error.
