* HISTORY
* $Log: prim_type.h,v $
* Revision 1.12 2005/10/05 00:31:14 dhdfu
* Make int8 be explicitly signed (signedness of 'char' is
* architecture-dependent). Then make a bunch of things use uint8 where
* signedness is unimportant, because on the architecture where 'char' is
* unsigned, it is that way for a reason (signed chars are slower).
*
* Revision 1.11 2005/06/22 03:10:23 arthchan2003
* Added keyword.
*
* Revision 1.3 2005/03/30 01:22:48 archan
* Fixed mistakes in last updates. Add
*
*
* 12-Mar-1999 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
* Added arraysize_t, point_t, fpoint_t.
*
* 01-Feb-1999 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
* Added anytype_t.
*
* 08-31-95 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
