Re: [PATCHES] Patch to make Turks happy.

Are you 64-bit s390?

We have OS/390 patches in 7.4 but they were judged too risky for 7.3.
Attached is the patch.   Comment is:

    revision 1.103
    date: 2002/11/22 01:13:16;  author: tgl;  state: Exp;  lines: +29 -2
    TAS code originally written for s390 (32-bit) does not work for s390x
    (64-bit).  Fix it.  Per report from Permaine Cheung.
