* buildsym.c (struct pending_block): Move from buildsym.h.

	(pending_blocks): Likewise; now static.
	(pending_block_obstack): New global.
	(free_pending_blocks): Free blocks.
	(record_pending_block): Use pending_block_obstack.
	* buildsym.h (struct pending_block): Move definition to
	buildsym.c.
	(pending_blocks): Don't declare.
