Hi Volker:
I always thought that the MinGW build would be the default for the new build systems but reading your mail this apparently isn't true.Will the MinGW build just not be the default one or will it not work / not be supported at all? If not, will the MinGW changes just get lost in the old build infrastructure?
MinGW/MSYS is not forgotten. We had to focus on Cygwin to get past this milestone.
I will circle back and work on MSYS support, hopefully starting this week. Tim
