-# Defines and substitutes the following vars:
-#
-# DL_OBJS - Name of the object file that implements dynamic
-# loading for Tcl on this system.
-# DL_LIBS - Library file(s) to include in tclsh and other base
-# applications in order for the "load" command to work.
-# LDFLAGS - Flags to pass to the compiler when linking object
-# files into an executable application binary such
-# as tclsh.
-# LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib",
-# that tell the run-time dynamic linker where to look
-# for shared libraries such as libtcl.so. Depends on
-# the variable LIB_RUNTIME_DIR in the Makefile. Could
-# be the same as CC_SEARCH_FLAGS if ${CC} is used to link.
-# CC_SEARCH_FLAGS-Flags to pass to ${CC}, such as "-Wl,-rpath,/usr/local/tcl/lib",
-# that tell the run-time dynamic linker where to look
-# for shared libraries such as libtcl.so. Depends on
-# the variable LIB_RUNTIME_DIR in the Makefile.
-# MAKE_LIB - Command to execute to build the a library;
-# differs when building shared or static.
-# MAKE_STUB_LIB -
-# Command to execute to build a stub library.
-# INSTALL_LIB - Command to execute to install a library;
-# differs when building shared or static.
-# INSTALL_STUB_LIB -
-# Command to execute to install a stub library.
-# STLIB_LD - Base command to use for combining object files
-# into a static library.
-# SHLIB_CFLAGS - Flags to pass to cc when compiling the components
-# of a shared library (may request position-independent
-# code, among other things).
-# SHLIB_LD - Base command to use for combining object files
-# into a shared library.
-# SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
-# creating shared libraries. This symbol typically
-# goes at the end of the "ld" commands that build
-# shared libraries. The value of the symbol is
-# "${LIBS}" if all of the dependent libraries should
-# be specified when creating a shared library. If
-# dependent libraries should not be specified (as on
-# SunOS 4.x, where they cause the link to fail, or in
-# general if Tcl and Tk aren't themselves shared
-# libraries), then this symbol has an empty string
-# as its value.
-# SHLIB_SUFFIX - Suffix to use for the names of dynamically loadable
-# extensions. An empty string means we don't know how
-# to use shared libraries on this platform.
-# TCL_SHLIB_LD_EXTRAS - Additional element which are added to SHLIB_LD_LIBS
-# TK_SHLIB_LD_EXTRAS for the build of Tcl and Tk, but not recorded in the
-# tclConfig.sh, since they are only used for the build
-# of Tcl and Tk.
-# Examples: MacOS X records the library version and
-# compatibility version in the shared library. But
-# of course the Tcl version of this is only used for Tcl.
-# LIB_SUFFIX - Specifies everything that comes after the "libfoo"
-# in a static or shared library name, using the $VERSION variable
-# to put the version in the right place. This is used
-# by platforms that need non-standard library names.
-# Examples: ${VERSION}.so.1.1 on NetBSD, since it needs
-# to have a version after the .so, and ${VERSION}.a
-# on AIX, since a shared library needs to have
-# a .a extension whereas shared objects for loadable
-# extensions have a .so extension. Defaults to
-# ${VERSION}${SHLIB_SUFFIX}.
-# TCL_LIBS -
-# Libs to use when linking Tcl shell or some other
-# shell that includes Tcl libs.
-# CFLAGS_DEBUG -
-# Flags used when running the compiler in debug mode
-# CFLAGS_OPTIMIZE -
-# Flags used when running the compiler in optimize mode
-# CFLAGS - Additional CFLAGS added as necessary (usually 64-bit)
