Actually, the variable-size stack-allocated arrays of GNU C is "syntactic 
sugar" over a function called alloca(size) that does just the
same. However that function is not ANSI, not ISO and not even POSIX. It
seems to be rather confined to BSD & Linux.

Maybe I should stop my wanton use of that feature (i use the GNU C/C++ 
syntax, not alloca itself), because several systems (Ruby,Pd) are eager
to complain when the current stack content just _appears_ to be too big,
because that's how they detect an infinite recursion (!!!), so they
tend to choke when I put several *video frames* on the stack. :-]
