   		and the system supports pipes).  If a file is used, it
   		will be removed when no longer needed unless
   		PEX_SAVE_TEMPS is set.

		If PEX_LAST is set, and OUTNAME is not NULL, standard
   		output is written to the output file name.  The file
   		will not be removed.  If PEX_LAST and PEX_SUFFIX are
   		both set, TEMPBASE may not be NULL.

   ERRNAME	If not NULL, this is the name of a file to which
		standard error is written.  If NULL, standard error of
		the program is standard error of the caller.

   ERR		On an error return, *ERR is set to an errno value, or
   		to 0 if there is no relevant errno.
