Comment (by Phyx-):

 Your initial statement seems to be correct, it is the spaces in the paths.

 I can fix the `HSCOLOUR_CMD` one but I'm not sure what to do about the gcc
 tests.

 I don't think most of us use the platform to build, though it obviously
 should work. (though not sure what the status of bootstrapping using 8.0.1
 is).

 I don't know why the platform puts gcc on your path. Do you still have the
 issue if you just use GHC installed in msys2 per the instructions on the
 wiki?
