So it sounds like we've left out an #include <unistd.h> for building on 
Unix systems so the prototype will be visible.  That's a fix we need to
make.

Sure, that would be useful.  We announce beta releases on the 
address@hidden mailing list, which you can join here:

  http://www.unidata.ucar.edu/software/netcdf/docs/faq.html#maillist

We also have a read-only svn tree of the current stable snapshot, which gets
updated more frequently than beta releases:

  http://svn.unidata.ucar.edu/repos/netcdf/

but that's mostly for use by active developers.

Thanks for your offer to help test on specific platforms.  We can only test on 
a few combinations, and more is better ...
