__gc arrays

Hi,

I'm trying to port several C apps from windows to linux and I'd like to use pnet do this. However, I'm having problems getting bounds checking and garbage collection to work with C arrays.
In visual C++ .net, this can be done with the __gc keyword e.g:
int array[] = __gc new int[10];
Could someone tell me if cscc supports __gc arrays or is there another way of using standard C++ subscripting on managed arrays?

Thanks,
Alex Stephens
