Subject: [PATCH] [mcast-tools] Changing the type of pim_cksum.

Hello,

I could get access today (at last...) to a machine running glibc-2.3.4-2.13.
I had done the following:
git-clone git://git.linux-ipv6.org/gitroot/yoshfuji/mcast-tools.git

cd mcast-tools

aclocal; automake; autoconf
./configure
cd pim6sd
make

I got the following error:

In file included from debug.c:71:
../include/linux/pim.h:17: error: syntax error before "__be16"
../include/linux/pim.h:17: warning: no semicolon at end of struct or union
make[1]: *** [debug.o] Error 1
make[1]: Leaving directory ...
make: *** [all-recursive] Error 1

As far as I understand, the __be16 is good for kernel headers, but not
for user space headers. I am not sure about it. However, in case I am
right, I changed it to  "uint16_t pim_cksum" instead of  "__be16  pim_cksum"
in /include/linux/pim.h;
and then "make" finsihed ok.
And attached here is the patch. What do you think ?

Regards,
AJ
