True, but only while they don't require a recent guile.  And it'd be
possible to put out new header files for older versions of guile to
avoid that problem.  Sometime down the road the next version of guile
will be the old version of guile and this will be a big win for
application programs (i.e., users of Guile).  In the interim, it'll make 
reading Guile code more comfortable and maintainable.
