 I tried with different platforms/compiler combinations and I didn't
notice any dependency with the file suffix.
 - With Linux RH 7.3 and gcc-2.95.2 it works. But, the class
vector<double> in not in the std namespace.
 - With Linux RH 7.3 and gcc-3.2 it does not generate the class
information for vector<double> but it generates other classes involving
this one like __normal_iterator<A*,std::vector<A, std::allocator<A> > > 
 - With Windows and VC 6.0 it does not work.
