DOS port of GNUtar 11.2 with network and scsi support
 Compiles with Borland BCC 3.1

7/25/94:
 pick up hidden files both in wildcard expansion and directory
 recursion. In previous versions they were skipped unless mentioned
 on the command line.

6/20/94:
 move ^C/break check so it works with aspi as well as tcp
 force at least read access on restored files
 fix timestamp setting on r/o files

5/23/94:
 modified wattcp lib slightly to make work with "rsh -n" or
   redirect from /dev/null.
 using both --rshd and --wait on dos command line re-runs continuously
   until host passes --exit.
 passing --rshd in remote rsh command causes one more re-run
 passing --exit in remote rsh command ends re-runs
 fixed some more complaints from dos about not being able to
   change the modes on directories during restore.

3/23/94:
 working version with:
mostly prototyped functions
command line wildcard expansion plus @file inclusion
REGEX compiled out
  Not worth 50K to fuzzy-match volume headers.
  (probably should dump getdate as well...)
--archive
--reset-archive
  (need a short option for these)
--wait  (for remote rsh command)
--rshd  (for remote rsh command)
magic device names:
/dev/rexec
/dev/rsh
/dev/rshd
/dev/ct
/dev/nrct
Function pointers for easy addition of new ones.
#define for dos_chdir to make sure the right drive is selected
