Well that is the intention, but the real world is surprisingly
uncooperative in this area.

We all bear the weight of history. NetCDF was developed before
libtool, and before automake really got going. Only autoconf was used,
and hand-crafted make files, which are rather complex.

In 3.6.0 we upgraded to the latest autoconf version (we had been stuck
at version 2.13, now we're at 2.59.)

In 4.0 we add automake, and it helps a lot. (4.0 is due out this
Summer, with oodles of exciting new features, but full backward
compatibility with both classic and 64-bit offset netCDF files).

Someday I would like to use libtool on netCDF. But when, or even if,
that will happen, is something I can't say right now. It will not be
in the 4.0 release, nor, I think, the 4.1 release (which is off the
end of our schedule right now).

Well I would have thought that would have worked out of the box. I
have g95 around here somewhere, and I'll check to see what went wrong.
