Hi,
I just upgraded my laptop to RHEL5.2, kernel 2.6.18-92.el5, yesterday, and
then got the newest madwifi version, 0.9.4, since 0.9.3 wouldn't compile
anymore, but 0.9.4 doesn't, either.
I got the following error:

-----
I managed to "fix" it -- well, get it to compile -- by removing the
KERNEL_VERSION(2,6,22) section from include/compat.h (see below), since
that's where the errors seem to come from.
Not sure why that was necessary, since this is still kernel 2.6.18, but I
was just glad it worked, and I'll leave the proper fix to you. :)
Thanks a lot for a great driver,
Horst Severini
