D2 changes! Removed druntime from the repository again.. Sorry :/ Updated the druntime port a bit, now requires druntime from trunk. Added info in runtime/README on how to get druntime from trunk. Added patch to add LDC support to druntime. Removed some debug logging from D2 builds. Fixed broken typeinfo for const/invariant in D2.

module mini.const1;

void* g = cast(void*)&foobar;

int foobar()
{
    return 42;
}

void main()
{
    auto fn = cast(int function())g;
    int i = fn();
    assert(i == 42);
}
