I'm used to reading this stuff, so either way is fine with me.  Do we
have bit set / clear / read macros?

I agree, but I also don't want to construct the test string every time
or deconstruct the term string every time.  I could move the "T"
prefix string to a #define and use that both here and in
BOOLEAN_PREFIX_INTERNAL, but that solution may be worse than the
problem.  What do you think?
