I am trying to use variable-length arrays (advertised as an
extension of GCC) in G++ 2.4.5 compiling 80386 code for Linux.  I
can declare and use a variable-length array as an auto variable
in a function; however, trying to declare a variable-length array
as a function parameter (which the GCC info files claim is
possible) gives me an error message.  For example:

void gauss-seidel(int size, double A[size][size], double X[size],
                  double K[size], double epsilon)
{
  ...
}

when compiled gives the error

`size' was not declared in this scope

which appears for each instance of 'size' as an array dimension.

I have tried predeclaring 'size' with "int size; int size, ...",
which does not help.  Is this a currently supported feature of
GCC?  Is there something about G++ that I am unaware of that is
preventing the use of a variable-length array parameter?
