* libguile/numbers.c (scm_is_less_than, scm_is_greater_than): (scm_is_less_than_or_equal, scm_is_greater_than_or_equal): New internal functions. (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p): Use new helpers. Dispatch to generics if operands aren't real -- a tightening relative to the previous check which was just for numbers. * libguile/integers.h: * libguile/integers.c (scm_is_integer_less_than_ir): (scm_is_integer_less_than_ri): (scm_is_integer_less_than_zz): (scm_is_integer_less_than_zr): (scm_is_integer_less_than_rz): (scm_is_integer_positive_z): (scm_is_integer_negative_z): New internal functions.
