I think it should fail if GetShortPathName() returns 0. A 0 return value
GetShortPathName() failed. If it returns a 0, it did not modify the
buffer passed to it. cygpath allocates 1 byte and does a strcpy of the
buffer to that byte. If that's not a bug, I don't know what is.

Try your example, I don't think it will work. Maybe you meant to
use the '-w' option. It will work.
Your example does not work on my machine (XP). Using the cygpath
-d option causes GetShortPathName() to be called. It returns 0 and
sets the error to ERROR_PATH_NOT_FOUND. Using the -w option
is a different story. It will simply replace the "/cygdrive/c/" with "c:\".
don't think it calls a windows api to do this.
So in effect, the -d option causes a validation of the path and filename.
It cannot be used to convert an invalid directory name to a short filename.
