I've reproduced your problem with GCC 3.2, though the error messages are
slightly different. Digging a little deeper, the issue can be reproduced with
this
MPL-only snippet:

#include <boost/mpl/set/set0.hpp> /* include last to suppress compiler error
*/
#include <boost/mpl/map.hpp>

int main()
{
   return 0;
}

Is this also failing for your compiler version? I'm posting this in a
separate thread
as it seems to be a MPL-specific problem.

Best,
