2003-04-30 David Carlton <carlton@bactrian.org>

	* cp-namespace.c (get_namespace_objfile): Copy the namespace
	objfile's name.

	* block.h (ALL_BLOCK_SYMBOLS): Move here from dictionary.h.
	* dictionary.c: Sync up with mainline version I just posted.
	Specifically, update some commments, and:
	(dict_create_hashed): Fiddle with nsyms updating.
	(dict_create_linear): Ditto.
	(dict_lookup): Delete.
	(iterator_next_hashed): Delete FIXME comment.
	(iter_name_first_hashed): Replace 'sym' by 'sym != NULL'.
	(iter_name_next_hashed): Replate 'next' by 'next != NULL'.
	* dictionary.h: Sync up with mainline version I just posted: add
	inclusion guards, delete declaration of dict_lookup, delete
	ALL_BLOCK_SYMBOLs.

	* Merge with mainline; tag is carlton_dictionary-20030430-merge.
