Fair enough.  Is there likely to be any workaround in future or will 
extensions always be crippled in this way?  If it's limited to hydra 
couldn't it do an #ifndef HYDRA condition or so in the dgd source (from 
which, I assume, hydra inherits), adding the functions only in a regular 
dgd build?  I guess this is more work than I make it sound...?
