Thanks for the PR! On the arm CI builds, it has an error:

Unknown machine endianess detected. User needs to define ANYRPC_ENDIAN.

@dan-shaw Sorry for the late reply, I didn't find time to look into this earlier... Is there a way to retrigger the build and get some more information? It seems like the logs are no longer available...

@faaxm You should be able to see the logs now.

Edit: Let me know if you still can't.

@dan-shaw Found a way to patch anyrpc to know the endianness for ARM when built via VS.
I am not supper happy with this as I had to assume that compiling for ARM with visual studio is always for a little-endian ARM-platform, but to my knowledge that should be valid...

Do you know more about this?

Will eventually submit this patch to the anyrpc-repo....

Also... If this gets merged eventually, will you squash the commits? Or should I do a force push where the commit history is a bit cleaned up?

@faaxm Sorry for the delay. I believe compiling for ARM is always in little-endian on Windows. Other than that, the PR looks good. I will squash the commits then merge it - thanks for the PR!
