No, when I build gcc /opt/hi actually points to an empty area. Building
with /opt/hi
pointing to the place where all the stuff is actually installed causes
me a problem with
conflicting copies of libiconv. It's a bit of a mess because I'm
building a version of gcc
designed to run from /opt/hi on a machine with a bunch of stuff in
/usr/local/.
I suppose I might have to remove the conflicting packages from
/usr/local/ which is
not really a problem but means I have to be more careful about where
/opt/hi points
during various installs as the system will be more dependent upon
/opt/hi rather than
/usr/local/.

Thanks. I see that when /opt/hi/bin/ld etc are not found then the build
uses /usr/bin/ccs/ld.
Which is why my fudge of linking /usr/bin/ccs/as to /usr/local/bin/as
(Gnu) works.
