[Octave-bug-tracker] [bug #56267] addpath() on Windows fails to recognize same subdirs with different fileseps and case

[Markus Mützel]

Follow-up Comment #8, bug #56267 (project octave):

As we require that a directory already exists when we add it to the path, we
might be able to call GetLongPathNameW [1] to query (and add) the "canonical"
path of that directory.

Fwiw, here is what I see on Windows 10 with Octave 5.1.0:

>> canonicalize_file_name ('C:\USERS\Markus')
ans = C:\USERS\Markus
>> canonicalize_file_name ('C:\Users\Markus')
ans = C:\Users\Markus
