As an update on the Contributor License Agreement, it sounds like Lucasfilm may not have contributed to OSL before, so it's going through the approval process now! |

There was a problem hiding this comment.
I ran into this as well, but there is actually a better solution!

I think my Windows CI PR is going to subsume this. I still think you should push the CLA through the bureaucracy so you've got the ducks in a row for the next time somebody from ILM needs to make an OSL patch. But I suspect this PR is ultimately not going to be merged. |

No problem, Larry, and a set of Windows fixes directly from the OSL team is even better from my perspective. I'll close out this PR, but will continue with the Lucasfilm approval process so that we can contribute in the future. |

Tests
With these fixes in place, OSL builds on Windows now include
testshadeandtestrender, where these two applications would previously fail to build.For visual validation, I'm attaching the latest MaterialX render comparisons between GLSL and OSL, where the OSL renders are using the codebase in OSL main plus these two fixes.

Checklist:
already run clang-format v17 before submitting, I definitely will look at
the CI test that runs clang-format and fix anything that it highlights as
being nonconforming.
