   3 ## If for some bizarre reason the input file defines its own ___dso_handle, we
   4 ## should raise an error. At least, we've implemented this behavior if the
   5 ## conflicting symbol is a global. A local symbol of the same name will still
   6 ## take priority in our implementation, unlike in ld64. But that's a pretty
   7 ## far-out edge case that should be safe to ignore.
