The code assumes that __POWERPC__ always means Mac OS, breaking the build
because we don't provide Gestalt. Change the ifdef to avoid getting it picked
up. Fix improved by Brad (thanks!)
The hashcash tool allows you to create hashcash stamps to attach to
emails you send, and to verify hashcash stamps attached to emails you
receive. Email senders attach hashcash stamps with the X-Hashcash:
header. A hashcash stamp constitutes a proof-of-work which takes a
parameterizable amount of work to compute for the sender. The
recipient can verify received stamps efficiently.
