* src/function.c (parse_numeric): Check for empty value and error.
If we find ERANGE just print our own error, not strerror.
(func_word): Use a generic "not good" error message.
(func_wordlist): Ditto
(func_intcmp): Ditto
* tests/run_make_tests.pl: Remove code to find strerror(ERANGE)
* tests/scrips/functions/intcmp: Update the error message.
* tests/scrips/functions/word: Ditto.
Modify make functions that parse integer values to use long long
values instead of long: on Windows long is the same as int (4 bytes)
and we don't want behavior to differ between different platforms.
* bootstrap.conf: Change strtol module to strtoll module.
* src/function.c (parse_numeric): Use strtoll() and return long long.
(func_word): Use long long.
(func_wordlist): Use long long. Verify second argument is >= 0.
(func_intcmp): Use long long.
* src/config.ami.template: Don't define HAVE_STRTOLL.
* src/config-vms.template: Define HAVE_STRTOLL.
* src/config.W32.template: Define HAVE_STRTOLL.
* tests/run_make_tests.pl: Set $ERR_out_of_range to the proper string.
* tests/scripts/functions/word: Rework to use the new style and avoid
TAB characters. Verify trailing whitespace is ignored. Add a test
for a negative second argument to wordlist. Add tests for max signed
integer values. Use $ERR_out_of_range for the error string.
* tests/scripts/functions/intcmp: Add tests for min and max signed
integer values. Use $ERR_out_of_range for the error string.
Numbers can come from $(words ...), automatic variables such as
$(MAKELEVEL), from environment variables, or from shell output such as
through $(shell expr ...). The $(intcmp ...) function allows
conditional evaluation controlled by numerical variables.
* NEWS: Announce this feature.
* doc/make.texi (Functions for Conditionals): Document 'intcmp'.
* src/function.c (func_intcmp): Create the 'intcmp' built-in function.
* tests/scripts/functions/intcmp: Test the 'intcmp' built-in function.
