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.
