Hi,
KAME had removed ipprotosw.h from the KAME source repositry (for
FreeBSD4). Though this do not clean up the varargs functions, we
still think this is a better (or not worst at least) comprimise in a
current situation.
Also, I had made a patch for FreeBSD-CURRENT for the same purpose.
Please see and review the attached patch. If it looks OK, I will
commit it to the CURRENT tree.
Thanks,
---
