Gdbm files have never been `portable' between different operating systems,
system architectures, or potentially even different compilers.  Differences
in byte order, the size of file offsets, and even structure packing make
gdbm files non-portable.

Gdbm version 1.9 includes `large file' support, enabling it on operating
systems where it is not the default.  `Large file' support is essentially
when a system uses 64bit file offsets.  Gdbm has, of course, supported `large
files' on systems where it was the default for a very long time.

On some systems this functionality is not enabled by default. To enable it, 
build rpm with option --with=largefile. THIS MEANS THAT GDBM 1.9 MAY NOT BE 
ABLE TO ACCESS DATABASES CREATED BY PREVIOUS VERIONS ON THE SAME SYSTEM.

Running the `configure' script with the `--disable-largefile' flag should
produce a backwards-compatible build on such a system.  However, for maximum
compatibility, and increased functionality, you may want to have your
application produce a portable copy of your database with the 1.8.3 version
of the library, and then load it back into version 1.9.

Gdbm 1.9 contains a utility designed to help you produce such a portable
copy: gdbmexport.  To build it, configure the package with the
--enable-gdbm-export option.  For the information on how to use this
utility, refer to the documentation, chapter 17 "Export a database into
a portable format." (run `info gdbm gdbmexport' to access it, once
gdbm 1.9 has been installed, or `info -f doc/gdbm.info gdbmexport' to
access the shipped info file).
