$ gcc --version
gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3

(This is Ubuntu 10.10.)

The line in question is:
    libxl__xs_write(gc, XBT_NULL, libxl__sprintf(gc, "%s/bios", path),
                    libxl__domain_bios(gc, info));

Looks like libxl__xs_write() is expecting the 4th argument to be a
format string...?
