  cd /bin
  ln -s pwd foo
  ./foo		# works
  cat ./foo	# fails

Why does running foo work?  Because Windows CreateProcess call does not
need a .exe extension to run a program.  Why does cat fail?  Because
'foo' resolves to 'pwd' and, as far as the Windows CreateFile is
concerned, there is no file called 'pwd'.

So, what you are seeing is a side effect of the way windows operates.  We're
not going to change ln to automatically add a .exe extension.
