I thought (can't remember when/how I was told) that it was no longer
recommended to add
#ifdef INET
or
#ifdef INET6
to the kernel sources.
I'll admit I think #ifdef'ng code when it isn't necessary to get it to buil=
d makes the
code less readable and, as such, I prefer not to do this.
So, is this still recommended for blocks of code that only execute for the =
version
of IP, but will build for kernels that do not have the particular "options =
INET{6}"
in the kernel config?
If it is still recommended, I will do it, but I'll admit I don't understand=
why it should
be done? (All it does is reduce the size of the executable by a small amoun=
t and
that doesn't seem significant to me.)
