	1003	# files into an executable application binary such

	1005	# LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib",
	1006	# that tell the run-time dynamic linker where to look
	1007	# for shared libraries such as libtcl.so. Depends on
	1008	# the variable LIB_RUNTIME_DIR in the Makefile. Could
	1009	# be the same as CC_SEARCH_FLAGS if ${CC} is used to link.

	1011	# that tell the run-time dynamic linker where to look
	1012	# for shared libraries such as libtcl.so. Depends on
	1013	# the variable LIB_RUNTIME_DIR in the Makefile.
	1014	# SHLIB_CFLAGS - Flags to pass to cc when compiling the components
	1015	# of a shared library (may request position-independent
	1016	# code, among other things).
	1017	# SHLIB_LD - Base command to use for combining object files
	1018	# into a shared library.
	1019	# SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
	1020	# creating shared libraries. This symbol typically
	1021	# goes at the end of the "ld" commands that build
	1022	# shared libraries. The value of the symbol defaults to
	1023	# "${LIBS}" if all of the dependent libraries should
	1024	# be specified when creating a shared library. If
	1025	# dependent libraries should not be specified (as on
	1026	# SunOS 4.x, where they cause the link to fail, or in
	1027	# general if Tcl and Tk aren't themselves shared
	1028	# libraries), then this symbol has an empty string
	1029	# as its value.
	1030	# SHLIB_SUFFIX - Suffix to use for the names of dynamically loadable
	1031	# extensions. An empty string means we don't know how
	1032	# to use shared libraries on this platform.
	1033	# LIB_SUFFIX - Specifies everything that comes after the "libfoo"
	1034	# in a static or shared library name, using the $VERSION variable
	1035	# to put the version in the right place. This is used
	1036	# by platforms that need non-standard library names.
	1037	# Examples: ${VERSION}.so.1.1 on NetBSD, since it needs
	1038	# to have a version after the .so, and ${VERSION}.a
	1039	# on AIX, since a shared library needs to have
	1040	# a .a extension whereas shared objects for loadable
	1041	# extensions have a .so extension. Defaults to
	1042	# ${VERSION}${SHLIB_SUFFIX}.
	1043	# CFLAGS_DEBUG -
	1044	# Flags used when running the compiler in debug mode
	1045	# CFLAGS_OPTIMIZE -
	1046	# Flags used when running the compiler in optimize mode
