In reference to the practise of declaring a struct as:

struct blah {
  int num;
  char data[1];
};

From the FAQ 9.7:

   To be on the safe side, it may be preferable to declare the
   variable-size element very large, rather than very small; in the case
   of the above example:

		   ...
		   char name[MAXSIZE];
		   ...

   where MAXSIZE is larger than any name which will be stored. (The trick
   so modified is said to be in conformance with the Standard.)

I seem to remember hearing recently that even this modification is
not actually in conformance with the Standard, but I can't remember
why.  Can anyone enlighten me?

If it isn't, is there any way at all to portably achieve the desired
behavior (i.e. all the data in one contiguous block)?
