Branches: MAIN
CVS tags: HEAD

SHARC-porting aids that benefit generally:
Cross: Added non-byte-addressed architectures as possible target (not hosts
yet).
Rest: all types are now Gforth-private types (so you could define as Char
whatever you where like). Some messing around with inabilities of Analog
Devices port of GCC.
