Is the STL bundled with Visual C++ thread-safe?
The standard library shipped with Visual C++ 5.0 and 6.0 is not thread-safe, therefore you should not attempt to build multi-threaded versions of OpenTop using this library. However, the modifications required to fix the library are simple and Dinkumware have supplied patches which can be obtained from their web site: http://www.dinkumware.com/vc_fixes.html. Alternatively, you can use other third-party standard libraries which are thread-safe. One good example is STLPort.
