# the following is an excerpt from the tcl7.5b2 configure.in
#--------------------------------------------------------------------
#	The statements below define a collection of symbols related to
#	dynamic loading and shared libraries:
#
#	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_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 if
#			"${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 name of the shared library.  An
#			empty string means we don't know how to use shared
#			libraries on this platform.
#	VTK_SHLIB_BUILD_FLAGS -
#                       Flags to use when building a shared library.	
#	VTK_SHLIB_LINK_FLAGS -	
#                       Flags to pass to the compiler when linking object
#			files into an executable application binary such
#			as tclsh.
#--------------------------------------------------------------------
