Hello,

Adding Hollis, which I forgot in my initial e-mail. Hollis, please have
a look at the thread, there has been some other build errors on your
older build machine.

If the issue can be worked around by a patch, it's nice because we
don't have to propagate the host gcc dependency to gazillions of
packages. However, Hollis patch wasn't that simple/trivial, it would be
nice to have it checked by upstream. Or maybe it's just me who isn't
familiar enough with the semantic of atomic intrinsics.

Best regards,

Thomas
