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.
