[cfe-dev] Problem loading plugin dll into clang under Windows

[Marcel Schaible via cfe-dev]

Thanks Kim, for your help.

Unfortunately I have not found a solution. I have tried several 
combination (32/64bit) without success.

I suspect that the VS2017 build is not compatible with the latest 
greatest clang build.

If I find the culprit I'll post it here.
