Re: Android NDK - libobjc2

[Ivan Vučica]

Hi Emmanuel,

That's amazing! Could you send them here (in one mail as multiple attachments, 
and mark the order of applying)?

I'd love trying them out and, hopefully, applying them (or at least poking 
people about applying them) :-)

Regards,

Ivan Vučica
