Hm - my reading of C99 is that using array as a base of a
variable-sized array has become undefined behaviour (Annex J, 2.,
"Addition or subtraction of a pointer [.] produces a result that
does not point into, or just beyond, the same array object").
Since todays compilers over-optimize so aggressively i indeed
became so frightened that i only use the  notation, i think it's
called "flexible array" or something.
