To the contrary.  The problem is the ambiguity that "X:/foo" might
be either the absolute POSIX path $CWD/X:/foo, or the absolute DOS
path "X:\foo".  I have a patch which fixes your case, but not much
else.  The problem is that we historically allow DOS paths as input
at all.  That was a bad decision from the start, but you can't easily
change 25 years of history...
