Are you sure about that? If it did, that would be an astonishing bug. I 
cannot replicate the behaviour you describe:

py> posixpath.relpath("/a/b/c")
'../../a/b/c'


However, if you pass a path using \ to posixpath, it treats them as 
non-separators:

py> posixpath.relpath("\\a\\b\\c")
'\\a\\b\\c'


That's because the given path \a\b\c under POSIX represents a file named 
"backslash a backslash b backslash c" in the current directory, not a 
file named c in a directory b in a directory a.


If you still think this is an issue, can you Can you post a minimal set 
of code that demonstrates that problem? Also, please specify the Python 
version.


Thanks,
