Hash Function change between PHP4 and PHP5

Hello Stefan,

as said in private already. This pretty much looiooks like a take over
problem. And as a sidenote, loop unwinding with string algorithmns should
take care of byte alignment. Both said the code is damn wrong.

Hello,

I just realised, that between PHP4 and PHP5 we changed the hash function
used within zend_hash.h from DJBX33X to DJBX33A. The diff is here =>
http://cvs.php.net/diff.php/ZendEngine2/zend_hash.h?ws=0&r1=1.57&r2=1.58&ty=u

Does anyone remember the exact reason for that? Or was the change done
by accident when the loops were unrolled? I have no idea if there is a
big difference for our hashing needs, but I am just curious if we
changed it because of benchmarks...
