Attached below are diffs. They convert the hashing to do:
'@'..'Z'
It's not that great as a hashing algorithm since you end up with a
non-prime number that's reasonably close to a power of 2 for your number
of buckets, but hey.
It's possible one other place (in constmap) needs to be changed. DJB's
code scares me in its lack of constants and lack of subroutines to
factor away similar bits of code.
Test it and see if it works.
cheers,
