28 | * Modified by Herbert 04/19/97: | |
29 | * - added include for new header portab.h containing OS dependent stuff. | |
30 | * - changed occurrances of '/' as path delimiters to macro from portab.h | |
31 | * - changed the handling of the tmp directory -- will no longer always be | |
32 | * ".", if possible, environment variables "TMP" or, if not set, "TMP", | |
33 | * or, if not set "." will be used. | |
