Add -lgtop_backend_sysdeps' and -lgtop_backend_common' if dynamic

Browse Source 
2000-02-16  Martin Baulig  <martin@home-of-linux.org>

	* configure.in (LIBGTOP_LIBS): Add `-lgtop_backend_sysdeps' and
	`-lgtop_backend_common' if dynamic linking does not work.

	* libgtop-sysdeps.m4 (GNOME_LIBGTOP_DYNLINK): New macro to check
	whether dynamic linking works.
	(libgtop_use_gmodule): Set this to `yes' or `no' depending on
	whether dynamic linking of the backends work on the current system.
	(LIBGTOP_USE_GMODULE): New automake conditional.

	* acconfig.h (LIBGTOP_USE_GMOUDLE): Define this when dynamic
	linking of the backends work on the current system.
