Erik:
Please review this change to README-builds.html. I have updated all
references to the GNU make version to specify that we recommend 4.0 or
later on Windows. Cygwin has been shipping with 4.x for a long time
now and we have been using it internally since the source code layout
change. Using older versions of make, particularly 3.81 version
commonly used for JDK 7, has been known to cause trouble with the JDK
9 (post src reshuffle) build. While 3.82.x versions probably still
works in many cases, I would rather have us move to 4.x since there
are features there we would eventually like to be able to use.
Bug: https://bugs.openjdk.java.net/browse/JDK-8072023
Looks good to me-
