Build Status

As of 2016-03-27 gcc-trunk (GCC 6) and gcc-5-branch (gcc > 5.3) will
not build OpenCoarrays versions prior to this release, 1.4.0

The semantics of calling stop from a subset of images were
incorrect. This defect was reported by Anton Shterenlikht (@mexas) in
bug report #160. (Thanks Anton!) The fix for this bug required changes
to GCC as well as OpenCoarrays. As a result, starting with the
development versions mentioned above and the as-of-yet-unreleased GCC
5.4, OpenCoarrays will fail to build, unless using this release, 1.4.0,
or a future one.

If you want to use the latest development versions of GCC and
OpenCoarrays, you will need to use an OpenCoarrays release >= 1.4.0.

If you are using GCC 5.3 or older versions, OpenCoarrays 1.4.0 and
previous versions should continue to build as expected.
(However, bug
#160 may persist without upgrading GCC.)
