The freescale and similar mobile processor compilers don't support SFINAE and can't compile Polygon.  Clang also currently fails, but I don't know why.  The sun compiler fails also.

It may have changed recently, but last I looked the core algorithm implementation didn't depend on my SFINAE based interfaces and could be included directly without including the rest of Polygon.  You could then wrap that without having to include any of the header files that contain SFINAE based interfaces that don't compile on non-compliant compilers.
