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