bug#7387: 23.2; Emacs port to HP-UX ia64

[Maguire, Andrew (GE Energy)]

Yes I am using unexelf.c

I agree that changing the compiler should not be important, although it
is in the bit of code that atempts to rewrite an ELF binary!!!

I am attempting to down the dev code. Will take a while as I have to
learn to use Bazaar.
I am downloading emacs-23.2 directory by mistake, but will let that
finish and download the latest "trunk".
I cannot spend long on this unfortunately, but will see what I can
report back.

I downloaded the source of the HP managed port which appeared to also
have an Itanium binary for 22.3 from
        http://hpux.connect.org.uk/hppd/hpux/Editors/emacs-22.3/
I then compared that with the source tree from GNU.
There were a few changes but the configure program had been modified
with 
an "if HP-UX" block of code right near the start of the script. As I
said,
it looked a bit of a hack. 
Upshot was I managed to get as far as I described below after
integrating the few changes the above appeared to have.

I also did a google search and found an patch for HPUX and 23.2 by Peter
O'Gorman.
I have applied that.

Will get back if I get anywhere.
Thanks
Andrew

Did you use unexelf.c for dumping?

What kind of hacks?  Changing the compiler should not be very important.

Can you please try the trunk?  There have been some fixes for HPUX
specific problems.
