ufraw fails to compile using clang-3.4 and newer

[jeremyhu (Jeremy Huddleston Sequoia)]

New C++ diagnostics cause recent clang to report errors in ufraw

Fails: sudo port -v -s destroot ufraw configure.compiler=macports-clang-3.4

Works: sudo port -v -s destroot ufraw configure.compiler=macports-clang-3.3
