That's too old, the cutoff is 27-pre15.

Are you sure ? For how I read it, 28-0.pre13.5.1 is more recent
than 27-pre15, not older.

That's exactly the point of this warning (some distro like to
kill it), I think it spells pretty clearly what's wrong. Don't say I
did not warn you...

Oh, but I think I've seen these warnings forever in the last years ;)

If you run a custom kernel, I think you won't see any problems
running a custom version of Wireless Tools. They are available on my
web site, pretty easy to install, and have minimal
implications. Usually distro do no customisation of my tools.

Indeed - it's not a problem to me :)

However, I downloaded and built the wireless_tools.29.pre10.tar.gz
sources from your pages and the problem is still there - minus the
iwconfig warning... more precisely,

-git8 works
-git9 fails
-git11 fails
-git11 minus the reverts works, and says

[asuardi@sandman ~]$ iwconfig -v
iwconfig Wireless-Tools version 29
Compatible with Wireless Extension v11 to v21.

Kernel Currently compiled with Wireless Extension v21.

eth1 Recommend Wireless Extension v18 or later,
Currently compiled with Wireless Extension v21.

[asuardi@sandman ~]$ ldd /sbin/iwconfig => (0xb7f87000) => /lib/ (0xb7f72000) => /lib/ (0x46b0d000) => /lib/ (0x469d8000)
/lib/ (0x469bb000)

So I guess there's an actual bug that doesn't depend on the
wireless-tools. Or maybe it's wpa_supplicant that has to be
upgraded ?

[asuardi@sandman ~]$ rpm -q wpa_supplicant

On the other hand, FC6, which is in beta, contains already the
proper version of the tools. I have been monitoring the various distro
in the last few months before sending those WE-21 patches, and all
major distro have WT-28 in the pipeline.

Even if so, wireless-tools would be the only package I have to
build out of the FC5 distribution to keep up with the latest -git
snapshot of the Torvalds kernel... I'm not especially troubled
with this anyway. Perhaps you could push the Fedora folks to
be a bit more up-to-date with wireless-tools in their current
main version ?

Actually, you might be able to install the wireless-tools RPM
of FC6 of FC-dev onto your FC5.

Still listening on how to further research the issue... many thanks
in the meantime, ciao,
