-# SC_TCL_CONFIG_CFLAGS

-#

-# Arguments:

-#	none

-#

-# 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.

-#       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

-#                       into a shared library.
-#       SHLIB_LD_LIBS - Dependent libraries for the linker to scan when

-#       TCL_LIB_SUFFIX -Specifies everything that comes after the "libtcl"

-#                       by platforms that need non-standard library names.
-#                       Examples:  ${VERSION}.so.1.1 on NetBSD, since it needs

-#                       on AIX, since the Tcl shared library needs to have
