The word fixing is good, but what about getting rid of the QERR_ macros
too?

The easiest way to do this would be to just replace each macro with its
text. If the string duplication bothers you (it doesn't bother me very
much, btw) you could create wrappers say qemu_listen() or listen_errp()
or whatever.
