Tony Finch 138908b211 Avoid dead code warning when using a constant boolean 
The value of `sign_bit` is platform-dependent but constant at compile
time. Use a cast to convert the boolean `sign_bit` to 0 or 1 instead of
ternary `?:` because one branch of the conditional is dead code. (We
could leave out the cast to `size_t` but our style prefers to handle
booleans more explicitly, hence the `?:` that caused the issue.)
