[svn r316] Fixed array slice assignments like: int[] arr = ...; arr[] = 42; There was problems with most non basic types... Added an option to premake so we can do: premake --target gnu --no-boehm to disable the Boehm GC.

module tangotests.mem2;

void main()
{
    int* ip = new int;
    assert(*ip == 0);
    *ip = 4;
    assert(*ip == 4);
    delete ip;
    assert(ip is null);
}
