Pkgs checking for IPv6 .. (and getting it wrong)

["Martin S. Weber" <Ephaeton%gmx.net@localhost>]

Hoi.

I'm having a 4.0 RC 1 (and a -current 4.99.31) without IPv6
support, i.e. built with -V MKINET6=no (build.sh). Now I have
packages (like e.g. net/ORBit2) which check for usability of
IPv6 via #ifdef AF_INET6 .

Is this correct for them to do so? I.e. I have to put more
inet6 - related variables into build.sh to make AF_INET6 disappear,
too? Furthermore PKG_DEFAULT_OPTIONS=-inet6 gets ignored but ok...

Let's take ... gnome-media.

gmake[2]: Entering directory

from the configure:


if test $have_getaddrinfo = yes; then
        
        cat >>confdefs.h <<\_ACEOF
        #define ENABLE_IPV6 1 
        _ACEOF

so getaddrinfo == IPv6 ?

Let's take ... net/ORBit2

it just checks #ifdef AF_INET6

Let's take ... net/vino

from its configure:

rm -f conftest.er1
cat conftest.err >&5
echo "$as_me:$LINENO: \$? = $ac_status" >&5
(exit $ac_status); } && {
 test -z "$ac_c_werror_flag" ||
 test ! -s conftest.err
 } && test -s conftest.$ac_objext; then
have_ipv6=yes
else
echo "$as_me: failed program was:" >&5
sed 's/^/| /' conftest.$ac_ext >&5

have_ipv6=no
fi

rm -f core conftest.err conftest.$ac_objext conftest.$ac_ext

if test "x$have_ipv6" = "xyes"; then

cat >>confdefs.h <<\_ACEOF
#define ENABLE_IPV6
_ACEOF

fi
else
have_ipv6=no
fi


... again : AF_INET6 defined means there's really IPv6 support?

Who's wrong here (besides me, the bad bad bad user who doesn't want ipv6 
support) -
the build system or the package checks ?

... hum hom ...
