I think setting it to a value of 0 has two good points...
In code that does:
if (XXX & RTF_LLINFO) {
yyy()
}
the optimiser should simply remove the code,
or at worst give an error messages that makes people go look for
the answer, and secondly,
the conditional
#if defined(RTF_LLINFO) && (RTF_LLINFO != 0)
can be easily used to make code conditionally do the right thing
for different versions of freeBSD,
possibly trivially replacing earlier occurances of
#ifdef RTF_LLINFO
