Hello

when trying to compile the latest batctl code from the git repository I
run into a compiler error
(gcc 4.8.5 and eglibc-2.18) .

As far as I could figure out the problem is caused by the define of
__unused in main.h. In my case
I use the libnl-3.2.25 to compile the code. The libnl header files include
the netdb.h header file
which uses __unused as an element of a struct. The define in the main.h of
the batctl code leads to a
compiler error. Renaming the define in main.h to something like __unused_
and corresponding
changes in the batctl code using __unused solves the compile time issue.
But due to my lack
of knowledge I don't know if this breaks the code.... On my devices batctl
seems to work properly
after changing this, but before sending a patch, I would like to ask you
guys first ;-)

Best regards,
Andreas
