Fails to build with GCC 14: "In function 'mysendto6': libndp.c:212:50: error: passing argument 5 of 'sendto' from incompatible pointer type [-Wincompatible-pointer-types]"

At building 1.8 (Gentoo downstream bug report: https://bugs.gentoo.org/922613) and also at building from git-master with GCC 14 I get:

You can test this? If I am correct that may solve your problem. #28

Applied your patch on top of libndp-1.8 and it works.

Thanks for your effort!
