This characteristics is needed as windows for historical reason
requested  ".exe" extension for all executable files, while
Unix have not such restriction.

So "cat.exe" is recognized by cygwin also as "cat".
Without this feature all scripts taken by traditional Unix's will
be broken and cygwin will be unusable.

Try this experiment on Linux:

touch foo
mkdir foo

does it work ?
