[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 neg;

void main()
{
    int i = 32;
    long l = 55;
    float f = 23;
    double d = 4;
    assert(-i == -32);
    assert(-l == -55);
    assert(-f == -23);
    assert(-d == -4);
}
