OK, lets give this a shot.  I'm pretty sure we'll start hitting some
OTHER bugs in SunPRO 5.3 when/if we fix this one, but its worth a try.

Here is the error message:
"/home/nbde52d/src/boost-regression/boost/boost/iterator/filter_iterator.hpp",
line 129: Error: Default arguments cannot be added in later
declarations of the template function in the same scope.

And here's the relevant section of code from filter_iterator.hpp:

    110   template <class Predicate, class Iterator>
    111   filter_iterator<Predicate,Iterator>
    112   make_filter_iterator(Predicate f, Iterator x, Iterator end =
Iterator())
    113   {
    114       return filter_iterator<Predicate,Iterator>(f,x,end);
    115   }
    116 
    117   template <class Predicate, class Iterator>
    118   filter_iterator<Predicate,Iterator>
    119   make_filter_iterator(
    120       typename iterators::enable_if<
    121           is_class<Predicate>
    122         , Iterator
    123       >::type x
    124     , Iterator end = Iterator()
    125 #if BOOST_WORKAROUND(BOOST_MSVC, == 1200)
    126     , Predicate* = 0
    127 #endif
    128   )
    129   {
    130       return filter_iterator<Predicate,Iterator>(x,end);
    131   }

I'm out of my league when it comes to fixing this.  What I do know is
that BOOST_NO_SFINAE is defined for this compiler, and enable_if does
NOT work.
