Browse Source 
with alloca, to avoid using random values from stack later on.
	* defs.h (fprintf_filtered):  Add prototype.
	* gdbtypes.c (check_stub_method):  Fix misleading comments.
	* gdbtypes.c (print_arg_types, dump_fn_fieldlists):  New maint
	support functions.
	* gdbtypes.c (print_cplus_stuff, recursive_dump_type):  Many
	small changes to maint support functions.
	* gdbtypes.h (cplus_struct_type):  Reorganize member ordering
	for some fields and expand comments.
	* objfiles.c (allocate_objfile):  Use new obstack_alloc_arg
	macro and track change to obstack_full_begin macro.
	* utils.c (fprintfi_filtered):  New function.
	* valprint.c (type_print_base):  Fixup field printing to not
	print extraneous lines and not print bogus "no data fields"
	messages for C++ classes with no data members.  Also use new
	fprintfi_filtered function.
