Created attachment 472648 [details, diff] compile fix for gcc7: abs() on unsigned int makes no sense calling abs() with unsigned int seems to be forbidden in gcc-7, so casting the parameters to int

This patch fixes build for both GCC-7.1.0 and Clang-4.0.0

Sorry I meant, why are you casting to int instead of dropping abs() and comparing the uints?
Created attachment 474608 [details, diff] ufraw-0.22-drop_superfluous_abs.patch abs() on uint is nonsense and gcc-7.1 refuses to compile this. So just drop the call to abs() in this case.
