Compiling for IPv6

[Simone Morandini]

Hi all,

I'd like to set up an IPv6 instance of BIRD for our members, but I'm 
having some troubles with "make".
When I issue "./configure --enable-ipv6" everything goes fine, but the 
subsequent "make" at a certain poing gives these errors:

[...]

On the same machine BIRD compiles successfully without the v6 option. Am 
I missing something basic here?
The box runs on a Fedora 12.

Thanks a lot,
Simone.
