Well, currently only "-lcaf_single". Unfortunately, there is currently
no working multi-image coarray communication library for gfortran. And
also the compiler does not yet generated all required communication calls.
ok, I just thought maybe I missed something.
The full support is planned - but it is unclear when it will be
completed. Recall, gfortran is essentially developed in the spare time
of only a few volunteers. Thus, new volunteers are highly welcome ...

sorry, I only know fortran (and a bit of unix),
so I doubt I can contribute.
I do send bug reports though.
Thanks
