Fixed a mistake in "help intro" where some inserted text
changed the value of "." and thus made the next result
incorrect.
Clarified in "help factor" that 1 is returned if no
factor below the limit was found.
Removed Makefile variable ${MAKEFILE_REV}.
The missing cscript/square.calc file has been restored.
Fixed compiler errors and warnings related to GCC.
In particular, gcc/9.3.1 and gcc/10.2.1 now compile
calc without any compiler errors or warnings,
even with -Werror -Wextra -pedantic.
To print out information about the calc compliation
environment, we added the following make rule:
make calcinfo
Improved how 'make debug' operates.
Moved help/contrib to CONTRIB-CODE. The help/contrib file
is now build from a copy of CONTRIB-CODE.
Created a new calc bug report Email address. Created a new calc
question Email address. Created a new calc contribution Email
address. See the BUGS file for details.
Added "help questions" to print the QUESIONS help file.
If the environment variable $CALCHELP is defined and is non-empty,
then calc help files will be in the direcgory by the $CALCHISTFILE
environment variable.
If the environment variable $CALCCUSTOMHELP is defined and is
non-empty, then custom calc help files will be in the direcgory
by the $CALCCUSTOMHELP environment variable.
The calc-tester mailing list has been retired. See:
