I'm not aware of any change in readlink in relation to the .lnk suffix 
for a long time.

Actually, isn't exim an old-style symlink?

  $ cd /bin
  $ attrib exim
     S       C:\cygwin\bin\exim
  $ ls --append-exe -l /bin/exim
  ls: cannot access /bin/exim.exe: No such file or directory
  $ ln -s exim-4.63-1.exe exln
  $ attrib exln
       R     C:\cygwin\bin\exln.lnk
  $ ls --append-exe -l /bin/exln
  lrwxrwxrwx 1 corinna root 15 Nov 24 09:50 /bin/exln -> exim-4.63-1.exe

It seems your .exe magic has a flaw when it comes to old-style symlinks
w/o .lnk suffix.
