+Bug#714923: opencv FTBFS on sparc64
+https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=714923
+
+opencv uses functions from <ext/atomicity.h>, but it wrongly assumes
+this functions apply to an int type. While it is true for some
+architectures, some architectures are using a long type there. The
+correct type to use is _Atomic_word.

-Bug#714923: opencv FTBFS on sparc64
-https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=714923
-
-opencv uses functions from <ext/atomicity.h>, but it wrongly assumes
-this functions apply to an int type. While it is true for some
-architectures, some architectures are using a long type there. The
-correct type to use is _Atomic_word.
