It does but with one little wrinkle.

Solaris < 8 also lacks struct if_nameindex in the system <net/if.h> and 
this caused a build error on Solaris 7 when I ran the build with gcc 3.4.6.

depbase=`echo test-net_if.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
        gcc -std=gnu99 -DHAVE_CONFIG_H -I.  -DGNULIB_STRICT_CHECKING=1 
-I. -I. -I.. -I./.. -I../gllib -I./../gllib -I/usr/tgcware/include -D
_REENTRANT  -g -O2 -MT test-net_if.o -MD -MP -MF $depbase.Tpo -c -o 
test-net_if.o test-net_if.c &&\
        mv -f $depbase.Tpo $depbase.Po
test-net_if.c:23: error: storage size of `ni' isn't known
make[4]: *** [test-net_if.o] Error 1

It turns out that if I use gcc 4.0 or later this error goes away but I 
think the proper fix would be to wrap the definition in !HAVE_NET_IF_H 
|| HAVE_IF_NAMEINDEX same as the code that uses it.
