Under macOS, to reduce dependency chains, we remove functions
and data that are unreachable by the entry point or exported
symbols. In particular, the macOS linker is used with both
"-dead_strip" and "-dead_strip_dylibs".
The libcalc shared library is now linked with libcustcalc.
Sort .gitignore. Add calc.spec to .gitignore.
Update format of header part of Makefiles.
Modify calc.spec.in to handle dynamic shared libraries with 3-digit
version numbers.
Under macOS, to reduce dependency chains, we remove functions and
data that are unreachable by the entry point or exported symbols.
In particular, the macOS linker is used with "-dead_strip".
While calc on macOS will execute if linker used with "-dead_strip_dylibs"
and CUSTOM is defined, other applications that use libcalc but not
libcustcalc (such as sample_many and sample_rand) will fail to execute
due to missile symbols. Therefore "-dead_strip_dylibs" is not used
by default when ALLOW_CUSTOM is "-DCUSTOM" under macOS.
Added Makefile variable ${VER} to holdthe calc major release version.
The calc major release version is a 3 level version (x.y.z).
Under macOS, the current version of both libcalc and
libcustcalc are set to the current calc major release version.
Under macOS, to reduce dependency chains, we remove functions and
data that are unreachable by the entry point or exported symbols.
In particular, the linker is run with "-dead_strip" and with
"-dead_strip_dylibs".
The macOS ld documentation states that option should not be used
when linking against a dylib which is required at runtime for some
indirect reason such as the dylib has an important initializer.
The libcustcalc appears to have such an initializer.
Under macOS, to reduce dependency chains, we remove functions and
data that are unreachable by the entry point or exported symbols.
In particular, the linker is run with "-dead_strip" and with
"-dead_strip_dylibs".
Dropped the use of Makefile variable ${SET_INSTALL_NAME}.
Under macOS it was always needed, elsewhere it was not.
Under macOS, the current version of both libcalc and
libcustcalc are set to the current calc release version.
Under macOS, to reduce dependency chains, we remove functions and

In particular, the linker is run with "-dead_strip".
Removed the ${CAL_PASSDOWN}, ${HELP_PASSDOWN}, ${HELP_PASSDOWN},
${CSCRIPT_PASSDOWN} Makefile variables as the new Makefile
include files keep Makefile variables in sync.
Fixed the ability of calc to compile when CUSTOM is undefined
(i.e., -UCUSTOM). The libcustcalc is always built, regardless
of the $(ALLOW_CUSTOM} Makefile variable. However when CUSTOM
is undefined, the bulk of custom functions are not defined.
Dropped support of Makefile.simple and custom/Makefile.simple.
The calc version 2.14.3.0 is the last release that supported
the Makefile.simple and custom/Makefile.simple files.
Now, a make that supports makefile conditional syntax is required.
The platform target section from the old Makefile has been moved
to a new file, Makefile.target. The Makefile.target is shared
by both Makefile and custom/Makefile. The custom/Makefile no
longer includes Makefile (instead it includes ../Makefile.target).
