/* $Log: sizes.h,v $
* Revision 1.8 1995/10/14 22:09:51 mike
* getting MAX__INT from values.h didn't really work since the value was
* unusable in an #if MAX__INT <= 0x7fff
* at least it didn't work under sunos -- so use of values.h is a goner
*
* Revision 1.7 1995/06/18 19:17:51 mike
* Create a type Int which on most machines is an int, but on machines
* with 16bit ints, i.e., the PC is a long. This fixes implicit assumption
* that int==long.
*
* Revision 1.6 1994/10/10 01:39:01 mike
* get MAX__INT from limits.h or values.h
*
* Revision 1.5 1994/10/08 19:15:53 mike
* remove SM_DOS
*
* Revision 1.4 1994/09/25 23:00:49 mike
* remove #if 0
*
* Revision 1.3 1993/07/15 23:56:15 mike
* general cleanup
*
* Revision 1.2 1993/07/04 12:52:13 mike
* start on autoconfig changes
*
* Revision 5.3 1992/12/17 02:48:01 mike
* 1.1.2d changes for DOS
*
* Revision 5.2 1992/08/27 03:20:08 mike
* patch2: increase A_HASH_PRIME

* Revision 5.1 1991/12/05 07:59:35 brennan
