Unfortunately this defeats the prime purpose of calling lstat().
The only benefit it would bring is to determine early if there's an issue with
the file and bail.
I would therefore suggest

#ifdef  DT_LNK
       if (...) {
       	  ...         
       } else

#endif
#ifdef S_ISLNK
       {
	...
       }
#else
	;
#endif

If that's OK with you I will commit this.

Thanks!

Cheers,
