Bug: https://bugs.openjdk.java.net/browse/JDK-8210880 Webrev : http://cr.openjdk.java.net/~prr/8210866/
As described in the bug, we can rely on the build platform for this file, as we do for most X11 include files. Builds pass on our core platforms. Since this is an X11 protocol file, I expect very few people will find they are missing this and have to install it .. -phil.
