dbxread.c (read_type): If we get "##", don't lookup_function_type 

and start clobbering it; allocate_stub_method instead.
	* dbxread.c (read_struct_type): Put "op$" instead of "operator"
	in the symbol table.
	* dbxread.c (read_struct_type): Set fcontext to 0 for normal member
	function.
	* dbxread.c (read_struct_type): Initialize name to 0.
	* dbxread.c (read_ofile_symtab, N_CATCH): Add offset to bufp->n_value.
	* dbxread.c (dbx_create_type): Zero TYPE_VPTR_BASETYPE.
	(read_struct_type): Don't bother to set TYPE_VTPR_{BASETYPE,FIELDNO}
	if it's just going to be {0,1}.

	* dbxread.c (virtual_context): Use TYPE_BASECLASS starting at 0
	(yes, it's #if 0, but just in case...).
