  You know what would come in handy here?  Some kind of automated tool for
processing these messes.  I imagine it would have to read in and parse a
bit of C code, building a syntax tree as it went.  It could even simplify
the expression somewhat by spotting duplicated subexpressions and 
eliminating them, or by applying mathematical transformations and boolean
algebra.  Obviously it would have to know all about C types and evaulation
rules, but hopefully it could then output the transformed code in some
simpler format.

  Oh.  Hold on a minute.  We already have one of those...
