Re: Pybind11 ver 3.0.2 errors

Hey everyone!

Thanks! That solved an issue for me:

Lately, the GNU Radio MinGW CI has been failing, but I have had a terrible time figuring 
out why. (I'm really not a fan of the Github runners, which make introspection of 
something failing basically impossible before it fails, local reproduction hard, and 
pairing that with rolling-release nature of Msys2 made it impossible to just look into 
what changed.

So, without Ryan pointing at this, and Gisle asking about it, I wouldn't have been able to 
figure this one out!

Should have asked, myself, it seems! Glad someone did :) Even more glad some answered!

Best regards,
Marcus
