This set of patches introduces a new tc7 code scm_tc7_number for

Browse source 
numbers.  Bignums, reals and complex numbers are turned from smobs
	into subtypes of scm_tc7_number.

	* tags.h (scm_tc7_number): New.

	* eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c
	(scm_self_evaluating_p), gc-card.c (scm_i_sweep_card), gc-mark.c
	(scm_gc_mark_dependencies), goops.c (create_smob_classes), hash.c
	(scm_hasher), numbers.c, numbers.h (SCM_NUMP), objects.c
	(scm_class_of), print.c (scm_iprin1), smob.c
	(scm_smob_prehistory): Don't handle bignums, reals and complex
	numbers as subtypes of scm_tc7_smob any more.

	* numbers.h, tags.h (scm_tc16_big, scm_tc16_real,
	scm_tc16_complex): Moved definitions from tags.h to numbers.h.
