I do have openssl 0.9.8 installed and patched and now when I run make I think I'm having problems with the ipw2100 drivers.  Can someone tell me which version of ieee80211 and ipw2100 work with 0.4.4?  I'm currently using Fedora Core 4 which uses a flavor of kernel 2.6.11.

You can fix this with the patch below or by getting a new snapshot from
the Host AP CVS repository. As a workaround, you should also be able to
just remove CONFIG_EAPOL_TEST=y from .config and ignore this compiler
warning.
