-#                       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 ${CC}, such as "-Wl,-rpath,/usr/local/tcl/lib",
-#                       that tell the run-time dynamic linker where to look
-#                       for shared libraries such as libtcl.so.  Depends on
-#                       the variable LIB_RUNTIME_DIR in the Makefile.
-#       SHLIB_CFLAGS -  Flags to pass to cc when compiling the components
-#                       of a shared library (may request position-independent
-#                       code, among other things).
-#       SHLIB_LD -      Base command to use for combining object files
-#                       into a shared library.
-#       SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
-#                       creating shared libraries.  This symbol typically
-#                       goes at the end of the "ld" commands that build
-#                       shared libraries. The value of the symbol defaults to
-#                       "${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.
-#       LIB_SUFFIX -    Specifies everything that comes after the "libfoo"
-#                       in a static or shared library name, using the $PACKAGE_VERSION variable
-#                       to put the version in the right place.  This is used
-#                       by platforms that need non-standard library names.
-#                       Examples:  ${PACKAGE_VERSION}.so.1.1 on NetBSD, since it needs
-#                       to have a version after the .so, and ${PACKAGE_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
-#                       ${PACKAGE_VERSION}${SHLIB_SUFFIX}.
-#	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)
