A signed bit field of 1 bit length is not useful

[misra-c]

The use of a single bit is illogical on a target adopting two’s complement representation. The intention of the programmer may have been to allow for values of -1 and +1 (as well as zero), but such data values clearly require at least 2 bits (which in turn actually provides a range of -2 to +1). The ISO C standard does not define the required behaviour for a signed bit field of length 1.
