I don't have details of exactly what uses of flexible array members they 
were making beyond those permitted by ISO C.  I guess the general point is 
to be careful about disallowing such uses because it might break existing 
code (so allowing plenty of time before a release for distribution 
rebuilds to catch any problems with such a change, for example).
