Still some missing parts. I am a bit busy today but I am free to dig it
more at night.
I saw some issues related to flags that were already discussed on this ML.
And some other related for example to the "BUG()" macro.
Please let me know if I can help in something else.

Please find attached the log of the building with your patch.

Regards,
Vinicius
