FileZilla 3.28.0 does not build on Mac OS X <= 10.11 (El Capitan)

For example, on El Capitan, building FileZilla 3.28.0 via MacPorts failed:

Do you still experience this if you add this at the top of src/interface/file_utils_osx.m?

#include <Foundation/NSURL.h>

Thanks, FileZilla 3.29.0 now compiles on 10.9 and later.

It breaks on 10.7 and 10.8 though:

Is this functionality required?

[Tim Kosse]

FileZilla requires OS X 10.9 or higher.

OK. I would bet that I managed to compile at least filezilla on 10.7 a few days ago. C++ standards are no longer a problem, but if a new SDK is needed, there's not much point in trying.
