My point is on a unix system ':' is an allowed file/directory name.

Let me put it another way

c:/blah is an absolute on a dos based filesystem, but relative on a unix
based filesystem.

Therefore code which unconditionally assumes that kind of path is absolute
or relative is broken since the interpretation of that path is dependent
on the host filesystem.
