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