egcs, more c++/g++ warning patches

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

Jason,

	Here are some more warning patches for the gcc/cp directory.
Okay to install?

		--Kaveh




Sun Sep 27 20:58:43 1998  Kaveh R. Ghazi  <ghazi@caip.rutgers.edu>

	* Makefile.in (spew.o): Depend on toplev.h.

	* call.c (compare_ics): Initialize variables `deref_from_type2',
 	`deref_to_type1' and `deref_to_type2'.

	* decl.c (init_decl_processing): Remove unused variable
	`ptr_ftype_void'.

	* except.c (get_eh_type): Hide prototype and definition.
	(process_start_catch_block_old): Remove unused static prototype.

	* pt.c (tsubst_decl): Initialize variable `argvec'.

	* spew.c: Include toplev.h.
