 I get the following error (repeated several times) when I build the boost
 libraries using MSVC 8.0 (8.0.50727.42):

 ...failed compile-c-c++ bin.v2\libs\regex\build\msvc-8.0\debug\link-static

         with

             _Ty=unsigned short
         ]

 Commenting out the line:

 template _CRTIMP2 allocator<unsigned short>::allocator();

 where it appears in usinstances.cpp and workaround.hpp seems to solve the
 problem. In the MSVC definition of this function, it includes "throw()",
 which causes the conflict.
