+#       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
