I have recently started evaluating two freely available C++ compilers for the Win32 platform: Digital Mars C++ and Watcom C++. Both compilers were only recently revived after a few years of no development and they therefore still lack a bit behind with the latest C++ language features.

Here are some quick&dirty C++ language conformance tests comparing these compilers (using the default settings).
