Is this correct for the LDPK_COMMON case that's also covered by the if()
that you alter in get_symbols()?

Adding to the (my?) confusion is that after said

      if (syms[n].def == LDPK_UNDEF
	  || syms[n].def == LDPK_WEAKUNDEF
	  || syms[n].def == LDPK_COMMON)

there's an "else if" with this comment:

      /* Was originally def, weakdef, or common, but has been pre-empted.  */

With the cited if(), no originally common symbol can make it there, can it?
