Subject: [boost] [Polygon] Template error in CodeWarrior when attempting union on polygon_set_data

I hesitate to mark this as [Polygon] because the error message is in a
different part of Boost. However, I have little idea what the actual
cause of the problem is or what any of the relevant stuff even means, so
I figure [Polygon] is as good as anything at the moment...
As before, this is a custom version of CodeWarrior an embedded ARM
system, so I have no idea how well it corresponds with other versions of
Here is a trivial program that illustrates the problem, using the
BOOST_VERY_LITTLE_SFINAE patch from the last discussion here:
using namespace boost::polygon;
using namespace boost::polygon::operators;
ps += rectangle_data<int>(0, 0, 1, 1);
This results in the following error message :
Error : illegal use of template argument dependent type 'T::type'
The error occurs in this part of boost/mpl/aux_/preprocessed/plain/and.hpp:
template< typename T1, typename T2, typename T3, typename T4 >
struct and_impl< true,T1,T2,T3,T4 >
, T2, T3, T4
Any ideas about what's wrong or how to fix it?
