Subject svn commit: r719690 - /apr/apr/trunk/test/internal/testucs.c
Date Fri, 21 Nov 2008 19:52:45 GMT
Author: wrowe
Date: Fri Nov 21 11:52:44 2008
New Revision: 719690

URL: http://svn.apache.org/viewvc?rev=719690&view=rev
Log:
As I had gone ahead and built this table as part of another exercise,
it seems worth depositing it here, although the list is redundant for
our purposes.
