+       * peigen.c (pe_print_idata): Look for .idata section and print
+       info even if data directory has zero entries.  Read idata section
+       starting from dataoff, and adjust all data offsets to suit.  Cast
+       all bfd_vma vars to unsigned long before passing to fprintf.
+       * peigen.c (pe_print_edata): Similarly, look for .edata section
+       and print info even if data directory has zero entries.  Cast
+       all bfd_vma vars to unsigned long before passing to fprintf.

+       * peigen.c (pe_print_idata): Use bfd_section_size rather than data
+       directory size which may be bogus.
+       * peigen.c (pe_print_edata): Similarly.
