47 * HISTORY
48 * $Log: prim_type.h,v $
49 * Revision 1.12 2005/10/05 00:31:14 dhdfu
50 * Make int8 be explicitly signed (signedness of 'char' is
51 * architecture-dependent). Then make a bunch of things use uint8 where
52 * signedness is unimportant, because on the architecture where 'char' is
53 * unsigned, it is that way for a reason (signed chars are slower).
54 *
55 * Revision 1.11 2005/06/22 03:10:23 arthchan2003
56 * Added keyword.
57 *
58 * Revision 1.3 2005/03/30 01:22:48 archan
59 * Fixed mistakes in last updates. Add
60 *
61 *
62 * 12-Mar-1999 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
63 * Added arraysize_t, point_t, fpoint_t.
64 *
65 * 01-Feb-1999 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
66 * Added anytype_t.
67 *
68 * 08-31-95 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
69 * Created.
