builworld fails due to error in af_inet.c

I just ran buildworld using the latest current source.

It dies due to this error in line 385 of /usr/src/sbin/ifconfig/af_inet.c:

static void
warn_nomask(ifflags)

The compiler really doesn't like not seeing a type for ifflags and bails
out as the result.

Strangely enough, in_proc() a few lines later clearly has int ifflags in
its list of variables.

Setting ifflags to int in warn_nomask() fixes the build.

Wasn't this compile tested before it was committed?
