I've checked the beta3 code against the code we use (successfully).
In aes, the only differences are entry point changes caused by IBM
namespacing our variant of OpenSSL.
In sha1 there's an additional .align 16 directive here in Beta3
.globl sha1_block_data_order
.type sha1_block_data_order,\...@function
sha1_block_data_order:

None of those differences should cause compile failures. I can't get at the
build machine at present to check the gcc and binutils versions, email me
if you need that information at some point.
Note that this code does only compile for a 64 bit target. It doesn't work
with 32 bit code.

Doesn't help much, but we do use that code, and at least slightly older
versions do compile and run on 64 bit Z.
(I had to backport it from a later OpenSSL to 0.9.8, so I can't be sure I'm
using exactly the same asm at this point).
I'll double check tomorrow and see if there are differences between the
beta 3 asm and the version we use here.

The 1.0.0 beta 3 fails with the SHA1 asm code and in the AES asm code.
I haven't had a chance to look into this in any detail - just noting that
the
out-of-the-box build isn't working. ./config -no-asm works so the issues
are all
in the asm code.
0.9.8k passes make test, 0.9.8d fails make test in BN code.
./config
make
make test
