While compiling CppUnit 1.5.3 on Windows, TextTestResult.cpp compiles with errors because the symbol 'cerr' is undefined. Including <iostream> solves the problem.
The configuration this appears under is as follows:
Visual Studio 6.0 with Service Pack 4
Dinkum STL 2.33 (this is an upgrade to the STL that VC++ ships with and from the same company that made the version in VC++ - www.dinkumware.com)
