Changes: builds again;

August 22nd 2020 ivtools-2.0.3

* add Golang style "%v" format descriptor to comterp print func.

July 5th 2020 ivtools-2.0.2

* Change priority of "$$" (stream) operator to line up with other \ 
stream operators (i.e. ".." and "**").

June 30th 2020 ivtools-2.0.1

* Fix nested user defined funcs in comterp (the func() command).

* Change isalpha(), isdigit(), and isspace() funcs to return 0 or 1
  (instead of the bitmask which is returned for C).

* Add comterp_run utility script for hands-free launching of comterp scripts.
  Write scripts with this header:

   #! /usr/bin/env comterp_run

* Add csvfilt comterp script as an example of using comterp_run.
  After installing both try "csvfilt --help".

June 21st 2020 ivtools-2.0.0

Non-backward compatible changes from ivtools-1.2.11:

* Swap "$$" and "$" operators in comterp.  The \ 
"$$" operator is now stream() (which matches
  the other double-character stream operators - "..", "**", \ 
and ",,") and "$" is now list().

* Reverse the priority of ".." (iterate()) and "**" \ 
(repeat()), giving ".." precedence over "**".
  The reason is because ".." is more complex than "**", like \ 
multiplication is more complex than
  addition.

* Remove symmax() and symcnt() commands because they were redundant with symid() \ 
which accepts
  :max and :cnt keywords.

Other changes;

* remove patches directory, sourceforge102203.xml, aclocal.m4, README.cygwin, \ 
README.ivmkcm, and comtop.tgz

* migrated all CHANGES-* files to a CHANGES directory
