A recent (stable) compat-wireless/drivers compilation exhibited a great deal of warnings on an older kernel (2.6.24 to 2.6.30 I think). Is 2.6.24 still supported?
Also, there was an issue with 50-compat_firmware.rules. Ubuntu 8.04 looks for it at /lib/udev/rules.d/ which gave me severe problems with firmware loading and system freezes. I had to copy/symlink 50-compat_firmware.rules from /lib/udev/rules.d/ to /etc/udev/rules.d/.
Warning log (partial). It compiles, but warnings galore. Is anyone up for backporting?

Hi Hauke
To answer your questions. The compat-drivers I'm quoting is 3.7.6.1-stable and from the daily build tars (2.20.13).
GCC version is 4.2.3
C-D compiles, but as noted with a tonne of warnings. We have several servers with specific purposes running 2.6.24 kernels and I decided to try a C-D on them.
I guess the question now is, do we drop support for c-wireless/drivers for 2.6.24 - 2.6.29(?) and bump the minimum kernel to a 2.6.30?

What version of compat-drivers are you using?
What version of gcc are your using?
Some parts of compat-drivers are still compiling against kernel 2.6.24,
but I would not recommend using a so old kernel. I haven't done run time
testes with 2.6.24 for a long time.

Could you provide a patch for this, I do not have a ubuntu 8.04
installation any more, this is pretty old.

I do not get these warnings when compiling compat-drivers-3.8 against
kernel 2.6.30. There are some other warnings with gcc 4.7 therefor I
used "export KCFLAGS="-Wno-unused-but-set-variable"" with these old
kernels, newer kernel versions already do this in the main Makefile.
