If you look at the filesystem fstream_test, it is also failing with 
messages relating to __ctor. The case is straightforward inheritance from 
std::fstream classes; I have no idea why it causes a problem. The same code 
works correctly with every compiler it has ever been tried with, IIRC, 
including VC++ 6.0 and 7.0.

I've been waiting until we get the actual release version of VC++ 7.1 to 
report the __ctor problem.
