Re: RFC: Objdump: Dumping PE specific headers

Hi Fangrui,

OK, I have pushed an update which makes the output similar to that
from "objdump -p", but not quite the same:

   $ objdump -P header tests/test-section-flags.exe

tests/test-section-flags.exe:     file format pei-x86-64

   The update also adds support for some more PE machine numbers,
   and support for AOUT headers that are larger than 28 bytes.
   (Although I have not actually tested this feature as I could
   not find any sample executables use target specific AOUT headers).

Cheers
