Mike,

In theory this contains a bunch of constant defines for GDAL,
stuff like "gdal.GA_ReadOnly".  In practice I do not know if this
resolves to actual code in Java or not.

On linux the version handling is done differently by libtool
in order to be consistent with other linux shared libraries.
I think consistency with how things are done on other platforms
is less important than consistency with the general expectations
on the platform in question.
