From b2eedf2f5e685c0f6d59f41a6a2052f7a12cd13d Mon Sep 17 00:00:00 2001
From: Werner Koch <wk@gnupg.org>
Date: Wed, 3 Mar 2004 08:08:43 +0000
Subject: * hppa1.1/udiv-qrnnd.S: Alignment fix from Lamont Jones for Debian. 
 Taken from gnupg-1.3.

* longlong.h: Added PowerPC 64 bit code from GPM-4.1.2 but didn't
enable it yet.  Some whitespace changes in HPPA to fix assembler
problems on HP-UX.  From gnupg 1.3

* mpiutil.c (_gcry_mpi_alloc_limb_space): Better allocate
something even if NLIMBS is passed as 0.

* config.links: Updated system list to match gnupg 1.3.
