What about the MinGW build?

Recently there have been changes (7152336 : Enable builds on Windows with
MinGW/MSYS and 7181175 : Enable builds on Windows with MinGW/MSYS) which
enabled the MinGW build in the
http://hg.openjdk.java.net/jdk8/buildforest. 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
