[Vm-dev] Cannot build successfully latest VM

Hi Clement,
I let a comment on line 1972 of src/plugins/BitBltPlugin/BitBltPlugin.c
on commit

and another one in

The problem is that a local variable unskew was generated as unsigned int
instead of int in BitBlt, but we then test if unskew < 0 which is obviously
going to be eliminated as dead code...

I did not try to compile the VM, but I'm pretty sure this is related.
