Subject: [PATCH] Fix type of single bit bitfields

clang16 warns
trace.c:311:22: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion]

quash the warning by using an unsigned type to allow
an assignment of 0 or 1 without implicit conversion.
