svn commit: r1784388 - in /openoffice/trunk/main/sal/osl/unx: pipe.c sockimpl.h

Author: pfg
Date: Sat Feb 25 15:46:26 2017
New Revision: 1784388

URL: http://svn.apache.org/viewvc?rev=1784388&view=rev
Log:
i101100 - Fix some aliasing issues.

Undo unnecessary change from r1782205: using a union in oslSocketAddrImpl 
just makes the code more complex and doesn't improve aliasing.
