Well, I checked that the function used (realpath) has been present in GNU make
since something like 2006.  So we should be basically fine, but Windows path
names are always a dare anyway and I don't have a Windows system available
myself.

So I don't see much of an option rather than letting this cook in the next
unstable version release and see whether GUB makes it to the finishing line.

Does GUB actually run on Windows? I wasn't aware of that.

We could workaround by interposing a function that does something different on
windows.

Well, regarding GUB my experience is pretty much hearsay.  After thinking about
it, you are probably right that it never runs on the target system itself.  I
mean, that's sort of its point.
