	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

Anton
