I thought that gettext was no longer required, as it was included in
the local bfd build (from configure.in:)

        cd binutils/bfd && chmod +x configure && ./configure 
--with-included-gettext && cd ../..

We do need sed.  I guess OSX has none, or it is incompatible?

Is Fink so non-standard that it must be avoided?  What is the
canonical way to get gnu software on OSX?

OK, this is going in, but I think we can lose the -lintl too.  Anyone
want to try to verify?

I don't get this one, as we emulate sbrk here.  Where is the system
definition required?

OK.  This is quite ugly, but its a hack to begin with.  Suggestions
most welcome.

OK, I take it you are using objc/malloc.h.  We need configure code to
look for this, and bomb if it cannot find one, just on macosx.  I'll
take a stab unless someone else wants to.

May I suggest we also lose the diagnostic output on save-system on
this platform?

Thanks again!  Will post when something is checked in.

BTW, I'm pushing 2.6.8 (in the guise of 2.6.7) and all the apps
through the Debian autobuilder system before releasing 2.6.8.  Please
let me know of any other 2.6.8 issues you may be encountering in your
axiom work asap.  Bug fix only at this point, of course.

Take care,
