 * 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.
