Comment:

 Urgh, that's horrible :)

 Your proposed solution seems reasonable.  The only way I know of to tell
 whether this is a DLL or an executable is the argument to `hs_exit_`,
 which is true if it was called via `hs_exit()`, and false if it was called
 as a result of a standalone program exiting.
