But error_setg_errno() uses either strerror() or
g_win32_error_message(), depending on the host OS. I prefer that over a
blind strerror(), to be honest.
In general, it might make sense to introduce a qemu_strerror() (which
g_strdup()s strerror() on Linux, I presume, so it's compatible with
Win32); or to allow passing a NULL format to error_setg_errno() so you
only get the error string.
