gwenview @4.11.2 importer/fileutils.cpp:133:10: error: use of undeclared identifier 'mkdtemp'

Gwenview won't build on Mavericks, I believe the following is the error.

This doesn't appear to have been reported upstream, but the current upstream version appears to be 4.11.60, so it may have already been fixed.

As I said on the upstream bug report ( ​KDE bug 327211), now that I've had time to look into it, it builds fine with "#include <unistd.h>" added to fileutils.cpp.

That does raise the question of why it worked for everyone else, but that's an easy enough fix.

Thanks for the report, I committed the fix in r113197.
