Yes.  It's also applied when stat'ing si or access'ing something.  The
same rules apply.  Consider:

  if (access ("foo", X_OK) == 0)
    execve ("foo", ...);
  else
    error ("foo not executable");

Consider that every call of the application has some reason Cygwin
just can NOT double guess.  If you skip the .exe/.lnk tests, you're\
basically doomed in one scenario or the other.

Been there, done that, no joy.
