Subject: [PATCH] Use unsigned int type for 1-bit integer bitfield
In C++, signed integers are represented in two's complement. This also applies to signed bitfields.
A signed bitfield composed of one bit can therefore store a value in the range -1 to 0.
Assigning a value of 1 to such a bitfield should produce a warning since it is out of range of representable values.
Therefore fix this case by using unsigned int instead of signed int
