Hello,
Someone is testing my MacPorts recipe (portfile) for building Qt 5.4.0 for me
on OS X 10.7. He reports that the build procedure fails with an error message
that neither of us can make much of:

}}}
Can anyone here make sense of the error and indicate how to avoid it? We do
have a number of patches that we apply for MacPorts, but those don't
(shouldn't) affect anything related to qbasicatomic, not to my knowledge at
least.
I admit that I've never seen this kind of construct, assigning a keyword to a
function (constructor). Could it be that my tester isn't using a sufficiently
recent Xcode version on OS X 10.7, and the error stems simply from a compiler
insufficiency?
Thanks,
René
