+#
+# 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.
+# LD_FLAGS - 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
