The -Wextra flag bundle gained a new warning -Wcast-function-type. This complains if you cast between two function prototypes where the number of parameters or their data types are not compatible. Unfortunately we need such "bad" function casts for our event callbacks. It is possible to silence the warning by first casting to the generic "void (*)(void)" function prototype, but that is rather ugly to add throughout libvirt code. Signed-off-by: Daniel P.
