CodeBlocks + MinGW + JUCE 4.3.1 = success with some fixes

Hi! Just wanted to share how I managed to use JUCE 4.3.1 with CodeBlocks/MinGW. First, in the UWPUIViewSettings class there were two template specializations which had to be moved outside the class. Next, in WebBrowserComponent there was an undeclared ::WebBrowser symbol (can anyone please explain what this is? thanks), resolved by substituting __uuidof (WebBrowser) with its GUID. With these changes, everything compiles well. However, of all unit tests, these ones consistently fail:
Starting test: Time / Timeā€¦
!!! Test 3 failed
!!! Test 27 failed
What are they and is this important? Thanks!
