-This option allows other files to be marked as executable and avoids the 
-overhead of opening each file to check for a '#!'.  The <literal>-X</literal>
-option is very similar to <literal>-x</literal>, but also prevents Cygwin
-from setting up commands and environment variables for a normal Windows 
-program, adding another small performance gain.  The opposite of these 
-flags is the <literal>-E</literal> flag, which means that no files should be 
-marked as executable.  </para>
