Yes, aside from imported headers we state: In the event that you require a specific width, use a standard type like int32_t, uint32_t, uint64_t, etc. The specific types are mandatory for VMState fields. Don't use Linux kernel internal types like u32, __u32 or __le32. in style.rst > > - vatsa -- Alex Bennée Virtualisation Tech Lead @ Linaro

Hmm I don't get that error when compiling on Linux. I think uint64_t will work better for all platforms where Qemu can get compiled? - vatsa
