Since base release 3.13 uses all ascii database description and
instance files, alignment problems should not occur (assuming that
all code is compiled by compatible compilers).
Since db2database and default.dctsdr both go away for 3.13
it is worth pursuing this problem. Note that by relinking gdct
to use the 3.13 libDb it works with 3.13 databases. Details are in
the WWW release notes.
