	* xcoffread.c (process_xcoff_symbol): Use new variables
	func_symbol_type and var_symbol_type as type of functions and
	variables which don't have any stabs associated with them.
	Reindent most of function.
	(_initialize_xcoffread): Initialize *_symbol_type.

	* xcoffread.c (read_xcoff_symtab): Reindent most of function.
	Put C_HIDEXT symbols in the minimal symbols, rather than ignoring
	them (this part commented out as I didn't quite get it to work).
	(cs_to_section, find_targ_sec): New functions, to support above code.
	* xcoffread.c (RECORD_MINIMAL_SYMBOL): Only skip '.' if it is
	actually present.
