Fix out-ouf-source build for runtime as well. To build out-of-source, follow these steps: # [[Insert LLVM build instructions here]] mkdir my_build_dir cd my_build_dir svn co http://svn.dsource.org/projects/tango/trunk tango ccmake <PATH_TO_SOURCE> # (Regular ccmake stuff, press 'c' a few times followed by 'g') make make runtime # add `PWD`/bin to PATH closes #213

void main()
{
    int[4] a = [1,2,3,4];
    int[4] b = [5,6,7,8];
    a[] += b[];
    assert(a[0] == 6);
    assert(a[1] == 8);
    assert(a[2] == 10);
    assert(a[3] == 12);
}
