Dump done between Tru64 and other platforms

[CR #369510]  The compatibility for a dump between True64 and other platforms was resolved. A database dump from True64 can be loaded to other systems. However, as a side effect to this fix, earlier dumps performed prior to this fix on True64, Adaptive Server Enterprise 12.5.3 esd #2 and earlier, are incompatible.

Workaround: In order to bypass the new behavior, start backupserver with trace flag: -D128, and older dumps can then be loaded into a True64 server.
