[PATCH] Fix iroute netmask computation This rewrites computation of the netmask from CIDR netmask. It was previously completely buggy due to using j instead of k. Using doubles to store a 32bit value is not really safe, and using masks and shifts is much simpler actually.
The upstream source provides no way to extend the CFLAGS by -g which is needed for building the debug package. So instead of setting the variables, we add to them.
