c++ variable-length array?

[Neal Becker]

Using gcc-4.1.1.  Info says variable-length array is supported in c++ mode,
but doesn't seem to work:

#include <boost/range.hpp>
#include <vector>

template<typename in_t>
void F (in_t const& in, int size, int x[size]) {}

void G (std::vector<int> const& in, int size, int x[size]) {}

int main () {
  std::vector<int> i (10);
  int x (10);
  F (i, boost::size (i), x);
  G (i, boost::size (i), x);
}
g++ -c Test.cc -I /usr/local/src/boost.cvs
