Having now updated to 8.0.4, I can confirm I get the same output from  
CCompilers[Full] as listed above, but MinGW-w64 still works correctly  
using the same modifications as worked for 8.0.1. Given Oliver  
Ruebenkoenig's statement that the other compilers are also still supported  
just as before, I presume the same is true for Visual C++ as well.  
Therefore, a configuration issue specific to your computer looks  
overwhelmingly likely.
