Hmm, since I just fixed B2DPlugin, there is no need to attach anything.
pick latest build once Travis has finished (or rebuild from source).

I broke the signedBitShift: used by B2DPlugin which might easily explain
having only one quadrant right (the + + combination).
I broke it on march 10 by my attempt to fix Crypto plugin...
Sounds weird, but I had to change the Slang CCodegenerator so as to
generated correct bit shifts...

This is one of the most dangerous and scary operations.
Since then, I did only eat my 64 bits dog food which did not show the bug
Instinct probably kept me away from rotten 32 bits meat :(
