Okay, but we still support those versions of Windows, right?

Yes, libiberty is working fine, except that GDB is not using
lrealpath, AFAIK.

And then the question is whether it is correct to resolve d:foo
etc. assuming thath the current drive and directories are identical to
what they were when the source was compiled.  Many projects use
recursive Makefiles that cause the compiler change directories at
will.
