RFR (7152336): Enable OpenJDK builds on Windows with MinGW/MSYS

[Volker Simonis]

Hi Tim,

I'm really happy to see that you are now taking care of this!

The link to the referenced e-mail thread doesn't seem to work, so
here's an alternative link:

"RFR (M): Enable OpenJDK builds on Windows with MinGW/MSYS"
http://old.nabble.com/RFR-%28M%29%3A-Enable-OpenJDK-builds-on-Windows-with-MinGW-MSYS-td33466599.html

And yet another link to an older mail thread which gives some
background information and finally led to the proposed MinGW change:

"Is anyone able to build on Win 7"

Regards,
Volker
