patch for unsigned bitfields

[grahams]

Robert

There is a typo in your patch to system.h (see relevant
part of patch below). It might also be prudent to add ()
around the expression.

Also there are some uses of ONLY_INT_FIELDS in cp/cp-tree.h
and java/parse.h which should also use the new ENUM_BITFIELD.
