Hi!
Using cygwin 3.3.4-2 and 3.3.5-1:
Create a file named 'file.ext.exe'.
In cygwin, run:
> touch file.ext
Examine the directory. The 'file.ext' wasn't created; the file
'file.ext.exe' timestamp was updated.
procmon shows this log for a non-existing file access by touch:
> touch.exe 17588 CreateFile D:\Documents\nonexistent.ext NAME
