FYI: Fix to varobj.c commited

[Fernando Nasser <fnasser at cygnus dot com>]

I commited the following change:

2000-10-13  Fernando Nasser  <fnasser@totem.to.cygnus.com>

	* varobj.c (varobj_update): Prevent uninitialized error code to be
	returned on type_changed.  Also, prevent value_equal() to be called
	for the types we do not want to test for updates.
