OK, so it does look like it picks the kernel uapi/asm/ptrace.h. It builds fine on Debian stable (no GCS anywhere) with including asm/ptrace.h and removing struct user_gcs. But I think we should include asm/ptrace.h in libc-gcs.h and not the gcs-util.h header (for NT_ARM_GCS it's fine to keep in gcs-util.h). -- Catalin
