Thanks! Do I need to be added for the Imath repo separately? It looks like its still failing the automated check ... |

Nevermind @xlietz - the CLA seems to be working now! Thanks! |

PR AcademySoftwareFoundation#250 changed the %lx to %llx to suppress an MSVC warning, but it introduced a gcc warning, where uint64_t is long, not long long. Better to leave it as %lx and just cast to long. It's only a printf anyway. Signed-off-by: Cary Phillips <cary@ilm.com>

MSVC is fairly picking about casts that potentially loose precision. This made up the bulk of the warnings that occur out of the box on windows.
None of these are particularly serious and they almost all occur inside unit tests, but hopefully by fixing them it makes it more obvious if there are new warnings introduced in the future.
