No sweat. I learned something about pybsddb3 in the process ;-)  (and  
that rpm still pisses me off...)

Hmm.  I poked around in the cvs logs & I saw the stuff related to mmap  
on windows. I figure that's the 'big fix' and I expect I'll be wanting  
that ;-)

ne'ertheless, it does seem that my build problem lies elsewhere...

Thanks!  That's a big help.  I was in the process of trying to  
handcraft a gcc invocation to get the job done.  Whether I do that, or  
do the -c thing though, I get errors about snprintf not being defined:
