* libguile/procs.h: Move subr macros to gsubr.h. * libguile/procs.c (scm_c_make_subr, scm_c_make_subr_with_generic) (scm_c_define_subr, scm_c_define_subr_with_generic): Remove these, because they deal in subr types, and now there is only one subr type. The body of this code is now in gsubr.c. * libguile/deprecated.h (scm_subr_p): Remove from procs.[ch] and define as a deprecated macro. Only used internally, but who knows who's out there. * libguile/goops.c (scm_generic_capability_p) (scm_enable_primitive_generic_x, scm_set_primitive_generic_x) (scm_primitive_generic_generic): Use the new SCM_PRIMITIVE_GENERIC_P macro instead of calling scm_subr_p. * libguile/gsubr.h (SCM_PRIMITIVE_P, SCM_PRIMITIVE_GENERIC_P): New macros, to replace scm_subr_p and hacky checking for generic capability. (SCM_SUBR_META_INFO, SCM_SUBR_NAME, SCM_SUBRF, SCM_SUBR_PROPS) (SCM_SUBR_GENERIC, SCM_SET_SUBR_GENERIC, SCM_SET_SUBR_GENERIC_LOC) (SCM_SUBR_ARITY_TO_TYPE): Moved here from procs.h. * libguile/gsubr.c (create_gsubr): Inline the scm_c_make_subr definition here, and work for generics too. Removed a scm_remember_upto_here_1 that was added earlier in the year when meta_info was not being traced by the GC. Adapt callers.
