Patchset #3 (id:40001) has been deleted

[Bence, 2014-10-22 14:19:38]

Such code:
bool has_bit = flags & BITMASK
results in
warning C4800: 'int' : forcing value to bool 'true' or 'false' (performance
warning)
    
On the other hand,
if (flag & BITMASK) {
is just fine.  Weird.

Modifying CL to make win tryjobs happy.
