Beware that gcc does not conform to C99 in regards to the size of a
structure containing a flexible array.  For example:

  struct foo{ int i; char c; char arr[]; };

gcc-3.4.2/i386 reports sizeof(struct foo) as 8 and offsetof(struct foo,arr)
as 5; but C99 requires those values to be the same.  More here:
