 On Windows I get an assertion failure in void_cast.cpp line 225 with the
 following scenario:

 DLL 1 has concrete class C which inherits from virtual B, which inherits
 from virtual A. BOOST_CLASS_EXPORT(C) is used.

 a static C exists.

 DLL 2 has concrete class D which inherits from virtual B.
 BOOST_CLASS_EXPORT(D) is used.

 a static D exists and will be instantiated when the library is loaded.

 main.cpp - contains an instantiation of D to make main.exe depend on both
 DLL 1 and DLL 2.

 this same test passes on UNIX.  It's as if on windows it is trying to
 register B twice.  Taking out the assert (as was the case in all previous
 boost versions) makes things work ok.
