  - Fix #101800 "[PATCH] Reinstate files to inc dir if deleted by external \ 
process"
      Periodic temp  directory cleaning programs (eg. "tmpwatch") may \ 
remove some
          (older) files from $PAR_TEMP/inc, but keep others. This causes the packed
	      program to fail.
    - When extracting a .par file to $PAR_TEMP/inc do NOT restore the original
          modified timestamps of the file (so that the extracted files have
	        the time of extraction as their modified time).
    - Add a "canary" file in $PAR_TEMP and back-date it 1 day. Hence \ 
any process
          removing files in $PAR_TEMP based on timestamps should remove
	        the "canary" before others.
    - If the canary file is missing, extract the .par to $PAR_TEMP/inc
          as previously was done only when $PAR_TEMP/inc was missing.
