Milter-greylist

Hello.

I had problem compiling milter-greylist 2.0.2 in older linux (pending.c: 
structure has no
member named `sin6_scope_id') and Emmanuel Dreyfus suggested to disable 
ipv6
support and add an #undef AF_INET6 after the includes in pending.c and 
it worked great.

However using same trick in milter-greylist 2.1.2 gives errors:

gcc -g -O2 -Wall -D_XOPEN_SOURCE=500 -D_BSD_SOURCE   -c -o 
milter-greylist.o
milter-greylist.c
gcc -g -O2 -Wall -D_XOPEN_SOURCE=500 -D_BSD_SOURCE   -c -o pending.o 
pending.c
