Good catch!  Even though I intended to have DLL-level backwards
compatibility, the lack of an appropriate declarations in the .h files
made this not work on Windows.  (And where does the source actually
say anything about uncommenting?  I couldn't find it :-)

The following -- untested -- patches should fix both problems.  Please
test and let me know if it works so I can add it to the distribution!
