OK, so we need to port the fseeko module to VOS.  And since you are the
first person that seems to be porting to this platform, you will have to
do much of the legwork.

But in the meantime, install m4 1.4.9, which did not use fseeko.  Your
dependency loop can go as old as m4 1.4.5 while still supporting modern
autoconf.

gnulib doesn't need to be installed, merely checked out.  If you have the
gnulib directory accessible from your VOS machine, you're done;
optionally, you can add that directory to PATH to use gnulib-tool without
a path prefix.

Once the gnulib directory is accessible, you can do the following to test
just fseeko and its dependencies:

./gnulib-tool --with-tests --test fseeko

gnulib-tool also has the --create-testdir option to create a smaller
directory that tests just fseeko, without having to copy all of gnulib
across OS boundaries.  But I'm not as familiar with that mode of usage.

It would be helpful if you posted the config.log of such a test, so we can
see why fseeko.m4 didn't detect that fseeko was missing on your platform.
