The problem is that DOS paths are treated differently, even within the
same program.
Take for instance, bash:

$ builtin test -x "$WINDIR\system32\cmd.exe" && echo ok
yes
$ builtin exec "$WINDIR\system32\cmd.exe" /C echo ok
-bash: exec: C:\WINDOWS\system32\cmd.exe: not found

That makes a lot of headache both for users and for programmers who
have to remember about all such special cases

Cheers
Ilya
