On Windows:

-----
import std.stdio;
import std.path;

void main()
{
    string absolute = r"C:\";
    string relative = r"\foo";

    assert(isAbsolute(absolute));
    assert(!isAbsolute(relative));

    writeln(buildPath(absolute, relative));  // writes \foo
}
-----

Interestingly if you swap the arguments around you get back C:\.

Python does it properly:

>>> import os.path
>>> os.path.join("C:\\", "\\foo")
'C:\\foo'
