calc

calc may be built with static or dynamic shared
libraries. The Makefiles were overhauled to use
system targets. Static and extern variables are
declared with CPP symbols. The calc library makes
it easier to control parse and scan messages.
Makefile.simple was added for hosts without GNU
Make. Custom registers were added. Support for MD5
and SHA-0 hashes was dropped. calc supports real
and complex exponentiation bases and exponents.

Documentation was written for the # operator,
comments, and cscripts. Multi-line statement
issues were documented. Builtins related to user,
system, and clock time were added. The runtime()
builtin output was changed.

This is a very minor update release to allow
OpenBSD-like make parsers to compile the source.
This is also a minor release to fix an issue under
Mac OS X where the make chk (and make check)
regression awk script did not run correctly under
Mac OS X 10.4.7. A few minor variables that were
not set to default values in lower level Makefiles
was fixed.

Documentation and regression tests for the builtin
quomod() were fixed. Builtin functions estr() (to
repesent many types of values by text string) and
fgetfile() (to pass the rest of a file into a
string) were added. Several help files were
improved.
