Hack to make compiling the tango 0.99.8 runtime work. The gc has no module statements and the new frontend fails to find the imports. So I add an explicit include path to the runtime gc directory.

// idouble

module typeinfo1.ti_idouble;

private import typeinfo1.ti_double;

class TypeInfo_p : TypeInfo_d
{
    char[] toString() { return "idouble"; }
}
