Yes, you can't just change the number of streams, because the rest of
the metadata would be offset by the size of the missing stream header...

Thanks for your feedback! Indeed, empty streams should be allowed,
though it turns out the the guid stream must have at least an entry for
the Module Mvid (this is spelled out in the new spec, but not in the old
one that I used at the time I wrote that code: I guess I should go and
review all the reflection stuff with the new spec).

Now ildasm can diassemble our binaries, but PEVerify still gives
the following errors:

[IL]: Error: Unverifiable PE Header/native stub.
[IL]: Error: Module load failed.

This may be because we don't include the x86 stub to load mscoree...

When used with the /MD option it completes successfully:

All Classes and Methods in console.exe Verified
