-#
-# Arguments:

-#
-# Results:
-#
-# Defines 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.
-# MAKE_LIB - Command to execute to build the Tcl library;
-# differs depending on whether or not Tcl is being
-# compiled as a shared 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_LIB_FILE - Name of the file that contains the Tcl library, such
-# as libtcl7.8.so or libtcl7.8.a.
-# TCL_LIB_SUFFIX -Specifies everything that comes after the "libtcl"
-# in the 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 the Tcl shared library needs to have
-# a .a extension whereas shared objects for loadable
-# extensions have a .so extension. Defaults to
-# ${VERSION}${SHLIB_SUFFIX}.
-# TCL_NEEDS_EXP_FILE -
-# 1 means that an export file is needed to link to a
-# shared library.
-# TCL_EXP_FILE - The name of the installed export / import file which
-# should be used to link to the Tcl shared library.
-# Empty if Tcl is unshared.
-# TCL_BUILD_EXP_FILE -
-# The name of the built export / import file which
-# should be used to link to the Tcl shared library.
-# Empty if Tcl is unshared.
-# CFLAGS_DEBUG -
-# Flags used when running the compiler in debug mode
-# CFLAGS_OPTIMIZE -
-# Flags used when running the compiler in optimize mode
