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.
