It's not clear to me from your message if you know this, but it's easy 
to get that behavior on Cygwin.  Just change the cygdrive line in 
/etc/fstab to:

     none / cygdrive binary,posix=0,user 0 0

I've been running this way for many years now, and I have never traced 
any problem I've had with Cygwin to this practice.

I can't think of a good justification for creating single-letter folder 
names at the top level of a volume, so this seems like a problem that 
isn't likely to come up.

I think that's actually a feature.  Notice that "ls /" also doesn't 
include "cygdrive".  If it did, you'd get duplicate entries in "find /" 
commands, the locate(1) DB, etc.

That causes duplicate entries when you use the fstab solution.

For example, "find / -name sh.exe" would turn up both /bin/sh.exe and 
/c/cygwin/bin/sh.exe.

If the Cygwin filesystem naming scheme were perfect, you could say "find 
-name sh" and get the same results.  And then if you demand that 
find(1)'s readdir() calls include both sh and sh.exe entries to fix 
this, now you've created another duplicate entry problem.

The Windows to POSIX translation will always be imperfect.
