| 26 | * HISTORY | |
| 27 | * 02-Feb-86 Glenn Marcy (gm0w) at Carnegie-Mellon University | |
| 28 | * Added check to allow multiple or recursive inclusion of this | |
| 29 | * file. Added bool enum from machine/types.h for regular users | |
| 30 | * that want a real boolean type. | |
| 31 | * | |
| 32 | * 29-Dec-85 Glenn Marcy (gm0w) at Carnegie-Mellon University | |
| 33 | * Also change spacing of MAX and MIN to coincide with that of | |
| 34 | * sys/param.h. | |
| 35 | * | |
| 36 | * 19-Nov-85 Glenn Marcy (gm0w) at Carnegie-Mellon University | |
| 37 | * Changed the number of tabs between TRUE, FALSE and their | |
| 38 | * respective values to match those in sys/types.h. | |
| 39 | * | |
| 40 | * 17-Dec-84 Glenn Marcy (gm0w) at Carnegie-Mellon University | |
| 41 | * Only define TRUE and FALSE if not defined. Added caseE macro | |
| 42 | * for using enumerated types in switch statements. | |
| 43 | * | |
| 44 | * 23-Apr-81 Mike Accetta (mja) at Carnegie-Mellon University | |
| 45 | * Added "sizeofS" and "sizeofA" macros which expand to the size | |
| 46 | * of a string constant and array respectively. | |
