svn commit: samba r17842 - in branches/SAMBA_4_0/source/lib: ldb/replace replace

[vlendec at samba.org]

Author: vlendec
Date: 2006-08-26 17:19:58 +0000 (Sat, 26 Aug 2006)
New Revision: 17842

WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=17842

Log:
After talking to Simo, apply the next attempt to resolve the strnlen
problem. Timegm is the same. Simo says this is just a workaround, but it helps
for now. Feel free to revert.
