I see. When looking more closely in the fix for JDK-8020411, it turned 
out that it could do with some improvements:
a) since it really only applies to the closed sources, it could (and 
should) be done only in the closed sources.
b) it was actually incorrect, since it removed the ADDED_*FLAGS 
variables, which are needed for later use to check for incorrect 
additions to *FLAGS.

I am sorry your patch has become caught in this messiness. :( 
Nevertheless, I think the best way forward is that I create a new patch, 
that  reverts the JDK-8020411 in the open sources and re-implements them 
in the closed sources. I agree that your solution is better, and what we 
should have in the open sources. You shouldn't have to care about the 
TARGET_BITS_FLAG, it is an internal hack.

I'll start working on it immediately.
