Oddly enough, it also causes compilation errors on Linux; at least with
the kernel headers present in current Fedora 18:
CC libvirt_util_la-virnetdevmacvlan.lo
In file included from util/virnetdev.h:31:0,
from util/virnetdevmacvlan.c:64:
/usr/include/net/if.h:44:5: error: expected identifier before numeric
constant
In file included from util/virnetdev.h:31:0,
from util/virnetdevmacvlan.c:64:
/usr/include/net/if.h:111:8: error: redefinition of 'struct ifmap'
...
I'm not sure if this is related to the known kernel header bug (see the
big thread at
https://www.redhat.com/archives/libvir-list/2013-January/thread.html#00891),
but it definitely must be resolved before we can hoist 'struct ifreq *'
into a header that is included in multiple files.
