This is a good overall statistic to judge also the decrease in link time and
memory space, so I'm wondering how much you save here.  Anyone?  Even if it
is less than 100KB it might still be worth it since then many applications
could use netcdf without much increase in system resource needs.  Especially
tool-oriented applications that are kept around in executable form.

I would hope for a somewhat better prognosis.  What are the pitfalls?
