[fpc-devel]ipv6 resolving

[Johannes Berg]

Hi,

I've adjusted the netdb code to actually fix some things and resolve
ipv6 addresses, and follow cname pointers..

Attached is a patch :-)

Also attached is a test program but that will only work if you have ipv6
enabled and are connected to 6bone in some way. You can test the cname
resolving anyway though.
And the test program needs my other patch with ipv6 structures to work.
