Hello!

When I tried to build openvpn-1.4.1 today, configure produced the
following output. After some trivial debuging I realised that
netinet/ip.h, netinet/if_ether.h and resolv.h can not be included
by themselvs, but netinet/in.h must be includeed first. Oterwise
"struct ip_addr" will not be defined.
This is on Solaris9. I admit that the problem should be blamed on the
system header-files, but I tought that the strength of autoconf was to
work around system oddities like this.
