Solaris 7 and xinetd 2.3.11

Hi,

I get the following error when i try to make the xinetd 2.3.11.
I am running Solaris 7 on SPARC, using gcc 2.95, either gnu make or
Solaris make, both return the same error. It seems Solaris 7 does not
support IPv6, and the make is somehow calling the AF_INET6.

axi:/home/douglas/src/xinetd-2.3.11# make
cd libs/src/portable ; make CC=gcc CFLAGS='-g -O2  -I../../include'
install

Can anyone help? Thanks.
