Error building berlios driver: IW_MODE_MONITOR undeclared

Hi,

I just tried to build the recent cvs nightly tarball (from
at76c503a.berlios.de, v0.12beta14) on a Debian Woody system running
kernel 2.4.19.

I got the following error:

gcc -MD -O2 -Wall -Wstrict-prototypes -pipe -fno-strict-aliasing
-DCOMPILE_FIRMWARE_INTO_DRIVER -fno-common -Wno-sign-compare -Wno-unused

make: *** [at76c503.o] Error 1


The README says that the driver works on 2.4.x and 2.6.x. I successfully
build the driver on various 2.6.x-based systems.
Do I have to use an official release version? 0.11?

wireless-tools is v23-2.

Thanks in advance,

Regards,
