Hi All,

The build passed on xlC 13.1 with the makefile patch I proposed (good catch on the comments Volkar!).

With Volkar, Erik, Matthias, and Magnus all approving the change, it sounds like we're good to merge!

Volkar, can you do the honours?

Best Regards

Adam Farley IBM Runtimes

P.S. I approve the change too. ;)
