Socket header file

I have been recompiling various network routines. There is a problem
with the following header file:

Linux chaos 2.1.15 #7 Fri Dec 13 13:08:45 EST 1996 i586

/usr/include/linux/socket.h: * (cmsghdr, cmsg_data[])
/usr/include/linux/socket.h: unsigned char cmsg_data[0];
^^^^^^^^^^^^^
/usr/include/linux/socket.h:#define CMSG_DATA(cmsg) (cmsg)->cmsg_data
^^^^^^^^^^^
referenced as a pointer
In file included from /usr/local/include/sys/socket.h:5,
from nettest.c:11:
/usr/local/include/linux/socket.h:53: warning: ANSI C forbids zero-size
array `cmsg_data'

This should probably be:
unsigned char *cmsg_data;
instead of:
unsigned char cmsg_data[0];

I don't know how many things this would break.

Cheers,
Dick Johnson
