- Update to 2.12.19.0:
* Added notes to help/unexpected about:
display() will limit the number of digits printed after decimal point
%d will format after the decimal point for non-integer numeric values
%x will format as fractions for non-integer numeric values
fprintf(fd, "%d\n", huge_value) may need fflush(fd) to finish
* Fixed Makefile dependencies for the args.h rule.
* Fixed Makefile cases where echo with -n is used. On some systems,
/bin/sh does not use -n, so we must call /bin/echo -n instead
via the ${ECHON} Makefile variable.
* Add missing standard tools to sub-Makefiles to make them
easier to invoke directly.
* Sort lists of standard tool Makefile variables and remove duplicates.
* Declare the SHELL at the top of Makefiles.
* Fixed the depend rule in the custom Makefile.
* Improved the messages produced by the depend in the Makefiles.
* Changed the UNUSED define in have_unused.h to be a macro with
a parameter. Changed all use of UNUSED in *.c to be UNUSED(x).
* Removed need for HAVE_UNUSED in building the have_unused.h file.
* CCBAN is given to ${CC} in order to control if banned.h is in effect.
* The banned.h attempts to ban the use of certain dangerous functions
that, if improperly used, could compromise the computational integrity
if calculations.
* In the case of calc, we are motivated in part by the desire for calc
to correctly calculate: even during extremely long calculations.
* If UNBAN is NOT defined, then calling certain functions
will result in a call to a non-existent function (link error).
