Ok, you're using a much more recent version of GCC than I do. Nice,  
but "fixing" the "value computed is not used" warnings means checking  
each and every call to hv_store(), also making the code much less  
readable.

The "pointer [...] differ in signedness" warnings are here since a  
long time, but don't seem to be a problem. For a few, it seems to be  
a case of throwing some (u_char *) casts at the appropriate places,  
but I'd prefer to double check that it doesn't change anything at the  
binary level before applying these.
