00057  * Merging files from 64-bit branch into TRUNK.  May require another commit

00060  * Revision 1.1.1.1.2.1  2007/05/29 18:58:35  wcmclen

00067  * Revision 1.1  2004/08/05 23:51:44  arodrig6
00068  * grabed files from SS and broke up some of them
00069  *
00070  * Revision 1.2  2000/04/10 23:46:29  karu
00071  * converted all quad to qword. NO OTHER change made.
00072  * the tag specfp95-before-quad-qword is a snapshow before this change was made
00073  *
00074  * Revision 1.1.1.1  2000/03/07 05:15:17  karu
00075  * this is the repository created for my own maintanence.
00076  * created when spec95 (lisp and compress worked).
00077  * compress still had the scanf("%i") problem
00078  * DIFF from the repository I am using alongwith ramdass on /projects
00079  * need to merge the two sometime :-)
00080  *
00081  * Revision 1.1.1.1  2000/02/25 21:02:50  karu
00082  * creating cvs repository for ss3-ppc
