Comment (by dlwalker):

 Looking at Config's documentation, it seems that `BOOST_NO_IOSTREAM` is
 descriptive, not proscriptive.  It is meant to flag when an implementation
 doesn't have IOStreams installed (like free-standing environments), not
 disable IOStreams even when the compiler supports it.

 Rational's implementation is just one header file, so separating I/O will
 make things more complex, as opposed to libraries that are already a bunch
 of headers and so one more won't make too much of a difference.
