* bfd-in.h (BFD_NO_FLAGS, HAS_RELOC, EXEC_P, HAS_LINENO,
	HAS_DEBUG, HAS_SYMS, HAS_LOCALS, DYNAMIC, WP_TEXT, D_PAGED,
	BFD_IS_RELAXABLE, BFD_TRADITIONAL_FORMAT, BFD_IN_MEMORY,
	HAS_LOAD_PAGE, BFD_LINKER_CREATED): Moved to ...
	* bfd.c: Here.

	* bfd.c (bfd): Change cacheable, target_defaulted, opened_once,
	mtime_set, no_export, output_has_begun and has_armap to bit
	field.

	* bfd-in2.h: Regenerated.
