My guess would be that on your distro, the ERROR_H symbol gets defined 
somewhere outside of qemu.git/error.h, so as a result the declarations 
in the file are skipped. Can you retry the compilation after making the 
following changes to qemu.git/error.h?

diff --git a/error.h b/error.h
index 6361f40..c5f67a0 100644
