Isn't the whole reason for Cygwin actually to enable doing Unixy things
in Windows (that is, providing Windows/Unix interoperablity?

Also, to clarify:  I didn't mean DOS-specific pathnames, as opposed to
general Windows pathname (e.g., meaning 8.3-style vs. VFAT long names).
I just meant DOS-/Windows-style pathnames (as opposed to Unix-style
pathnames).
