	* __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
	SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
	SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
	generalized it to apply not only to C level functions but also to
	scheme level functions.

	* debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
	scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
	scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
	eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
	only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
	respectively.

	* deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
	SCM_IDSTMSK): Deprecated.  The macro definitions are moved from
	eval.h into eval.c and a copy is placed into deprecated.h.

	* eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
	into eval.c. This definition was not part of the API in any
	officially released version of guile and thus does not need to go
	through a phase of deprecation.
