Summary: check_dhcp SegV's on Solaris 9

Initial Comment:
Running check_dhcp on Solaris 9 produces a core:

[root at bern plugins]$ ./check_dhcp -i eri0 Bus Error 
(core dumped)

(gdb) run -i eri0
Starting 
program: /home/hmann/nagiosplug/plugins/check_dhcp -
i eri0

Program received signal SIGSEGV, Segmentation fault.
0x000127b8 in add_dhcp_offer (source=
        {S_un = {S_un_b = {s_b1 = 192 'À', s_b2 = 
168 '¨', s_b3 = 2 '\002', s_b4 = 1 '\001'}, S_un_w = 
{s_w1 = 49320, s_w2 = 513}, S_addr = 3232236033}},
    offer_packet=0xffbff9e8) at check_dhcp.c:774

((u_int32_t *)&offer_packet->options[x]));

If run with -v, it's transmits a good request, but it 
chokes on options in the reply.

This is on Solaris 9 with the GNU environment.

This was an alignment problem on Solaris.  Linux kernel fixes 
alignment so this was not seen there.  Memcpy takes care of 
proper alignment.  Tested on RHEL V3 U3, RHEL V4, FreeBSD 
4.10 (Thanks Stanley!) and Solaris 9 with the GNU env.
