* 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.

* Fixed mistakes in last updates. Add

|
* 12-Mar-1999 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
