Our network has a mixture of Sun 386's and Sparcs.  Most directories are
NFS mounted so they can be accessed from any machine.

I have just discovered that ndbm databases that have been created on a 386
cannot be accessed from a Sparc.  Inspection of the .pag file shows that
it contains pointers or offsets (used by the dbm routines); these pointers
are architecture-dependent ints.  When I try to read the file from the
wrong kind of machine, the pointer is interpreted with its bytes swapped,
and the dbm routines blow up.

Is this a known problem?  Does anyone have a workaround?
