I tried with a gdc compiler compiled by myself and I was able to 
compile and launch my first sample application using 
wxWidgets-2.8.
Now I have some work to do to fix all the remaining warnings and 
errors but I hope that wxD will be very soon an alternative to 
existing gui framework for D.
In a perfect world I should also work on the D libraries to add 
support for mingwXX winpthreads because for the moment the gdc 
compiler is generated using --enable-threads=win32. As long as it 
cannot use posix thread it cannot be an official package of 
msys2/mingw64.
