Re: libtool, gettext, and HP-UX ia64 shared libraries

[Bob Proulx]

Let me keep this issue alive and kicking.  Libtool is still broken on
HP-UX ia64.  But with this change it works.  I just don't know enough
about libtool to suggest where libtool would need to be modified in
order to make this a proper fix.

Does anyone know where the right place is to add the -L option
suggested here into libtool so that it works on HP-UX ia64?

Thanks
