Bob,

I sent a patch to libtool-patch about a week ago.  The patch
was against libtool-1.4e.  I will get the latest libtool.m4
from CVSweb and redo the patch.  It is fairly extensive 
reworking of the hpux code.  The email below wasn't intended
to be applied directly, instead it was for people who are
interested to check the changes without diff code getting
in the way.  It does somewhat more than just add PA64 support,
as it moves the hpux9 code into its own case in the C++
and standard shared library support macros and I need to know
how this will be received.  It isn't strictly necessary but it
does make modified the hpux10/hpux11 (really just hpux11)
configuration that much easier.  If there is a particular
maintainer of the hpux code, can they get in touch with me ASAP.

Many thanks

Ross
