I think Bernhard is right, it isnt, VLA is a C99 feature but not a C++ feature.

For other incompatibilities between ISO C and ISO C++, see

~>cat > xxx.c
void foo(int argc)
{
        int foo[argc];
}

~>g++ -c -pedantic xxx.c
xxx.c: In function `void foo(int)':
xxx.c:3: warning: ISO C++ forbids variable-size array `foo'
