Porting
-------

All known system and compiler dependencies have been isolated into two
modules: SYSINC, which is the system header file, and SYSDEP, which is
the system dependent code.  The code has been revised to conform to the
ANSI C standard and standard header files and library routines have been
used wherever possible.  You should rename the appropriate files for
your system to SYSINC.H and SYSDEP.C before building PARC.  The
following versions are supplied:

	C86 - Computer Innovations' C-86 for MS-DOS.  This
	      is the original ARC code which was removed.
	      I have made no attempt to keep this code up
	      to date with changes I have made and do not
	      have access to the compiler, so there is very
	      little chance of it actually working.

	MSC - Microsoft C for MS-DOS.  Tested with V5.01.

	USG - Unix System V.  Tested with Release 3.0.

	VMS - VAX/VMS.  Tested with Vax-11 C V3.0 and VMS V5.2.

If your system is not in this list, feel free to browse the existing
SYSINC and SYSDEP files.  You should be able to get most of the code you
need from one or another of them.  If you do create a new version,
please send me the files so that I can incorporate them into future
versions.
