	* Makefile.in (SUBDIR_PYTHON_OBS): Add python-block.o and
	python-symbol.o.
	(SUBDIR_PYTHON_SRCS): Add python/block.c and python/symbol.c.
	(python-block.o, python-symbol.o): New targets.
	* python/block.c: New file.
	* python/python-internal.h (block_object_type,
	symbol_object_type, symbol_to_symbol_object,
	block_to_block_object, block_object_to_block,
	symbol_object_to_symbol, gdbpy_initialize_symbols,
	gdbpy_initialize_blocks): Declare.
	* python/python.c (demand_python): Add find_pc_function function.
	Call gdbpy_initialize_symbols and gdbpy_initialize_blocks.
	(gdbpy_find_pc_function): New function.
	* python/symbol.c: New file.
