[rfa] varobj.c fix -Wuninitialized warnings

[Andrew Cagney <ac131313 at cygnus dot com>]

Hello,

The attatched supresses a few -Wuninitialized warnings in varobj.c.  It
also tweeks the Makefile so that varobj.c can be compiled with the
-Werror option.

ok?

	* Makefile.in (varobj.o): Delete special compile rule
	suppressing -Werror flag.
	* varobj.c (varobj_create): Initialize ``old_fi''.
	(varobj_update): Initialize ``templist''.
