Andreas -- as you know the issue is complex. Do you have a specific
proposal to make for X10?

Hi Andreas,
I agree with you.
We still don't have clear semantics for volatile as Vijay said in his
comment.
I added a comment about current implementation and left the issue open.

Hi Mikio,
I used 2.3, which is out of date. Thanks for checking!
This means XTENLANG-1808 is actually resolved?

Still, the semantics of @Volatile are not clear. C++ and Javas
volatile
have different semantics. It does not make sense to compile
@Volatile to
volatile in both backends.
