[Qemu-devel] [build-error] possible build error at the tip of the trunk? (dtc-related?)

[Aleksandar Markovic]

Hello, all

All of the sudden, the latest code doesn't build on my host: (the code from 
several days ago builds fine)

Do you know what would be the culprit? Is it my environment, or a genuine build 
error?

Thanks in advance!
Aleksandar
