calc: C-style arbitrary precision system Files

The following are the changes in this release:

    Calc has a new calc-tester mailing list.  This list is for those
    who are using/testing calc.  We also use this list to announce
    new versions of calc.  To subscribe to the calc-tester mailing
    list, visit the following URL:

	    http://www.isthe.com/chongo/tech/comp/calc/calc-tester.html

	This is a low volume moderated mailing list.

	This mailing list replaces calc-tester at asthe dot com list.

	If you need a human to help you with your mailing list subscription,
	please send EMail to our special:

	    calc-tester-maillist-help at asthe dot com

	address.  To be sure we see your EMail asking for help with your
	mailing list subscription, please use the following phase in your
	EMail Subject line:

	    calc tester mailing list help

	That phrase in your subject line will help ensure your
	request will get past our anti-spam filters.  You may have
	additional words in your subject line.

    There is a new calc bug report EMail address:

	    calc-bug-report at asthe dot com

	This replaces the old calc-bugs at asthe dot com address.

	To be sure we see your EMail reporting a calc bug, please use the
	following phase in your EMail Subject line:

	    calc bug report

	That phrase in your subject line will help ensure your
	request will get past our anti-spam filters.  You may have
	additional words in your subject line.

	However, you may find it more helpful to simply subscribe
	to the calc-tester mailing list (see above) and then to
	send your report to that mailing list as a wider set calc
	testers may be able to help you.

    The following makefile rules that were related to printing the
    upper values of the calc version, rules that were made obsolete
    in calc version 2.12.4.14, have been removed:

	calc_vers calc_ver calc_ve
	vers ver ve

    Noted that the hash() builtin function, internally known as
    quickhash (used for internal objects such as the associative
    arrays as well as other internal processes) uses the deprcated
    32-bit FNV-0 hash.  The use of this deprecated hash is sufficient
    for calc internal purposes.  Use of FNV-1a is recommended for
    a general non-cryptographic quick hash.
