[boost] [Boost.MPL] Patch for SunOS (nested_type_wknd.hpp)

From: Christopher Currie (christopher_at_[hidden])
Date: 2003-11-06 09:43:01

The following is a patch to workaround a bug Sun C++ with Boost.MPL. It 
adds the Sun compiler to the list of toolsets that need the nested type 
workaround. A test case is also attached, which demonstrates the error.

Thanks,
Christopher
