* defines.h, rubysig.h, signal.c: removed macro handling which should be done in configure. * configure.in (intrinsics.h): check if present. * ruby.h: include intrinsics.h if available. * bignum.c, marshal.c: include ieeefp.h if available. * missing.h (isinf): define as a macro if finite() and isnan() are available.
