Indeed.  This is why all paths generated using the pathname2 package
convert all forward slashes to backslashes.  Also, the various PathXXX
functions do NOT work with forward slashes.

To wit:

irb(main):001:0> require 'Win32API'
=> true
irb(main):002:0> PathIsRoot = Win32API.new('shlwapi', 'PathIsRoot', 'P',
'I')
=> #<Win32API:0x2c17be8>
irb(main):003:0> PathIsRoot.call("C:\\")
=> 1
irb(main):004:0> PathIsRoot.call("C:/")
=> 0
