* configure.in (sizeof ptrdiff_t): check for size of ptrdiff_t.

* include/ruby/ruby.h (PRI?PTRDIFF, PRI?SIZE): printf conversion
  specifiers for ptrdiff_t and size_t/ssize_t.

* insns.def (leave), marshal.c (long_toobig), transcode.c
  (str_transcode), vm_dump.c (control_frame_dump, stack_dump_each),
  (debug_print_register, debug_print_pre): t and z length modifiers
  are C99.
