* configure.in (RUBY_REPLACE_TYPE): does not define rb_ prefixed

name if no default type is given.

* configure.in (RUBY_DEFINT): checks size.

* include/ruby/ruby.h (VALUE): use uintptr_t if available.

* include/ruby/ruby.h (PRI_PTRDIFF_PREFIX, PRI_SIZE_PREFIX):
  assumes usable if PRIdPTR is defined.
