Here are my comments concerning the other c99 options:

What's the behavior if one gives several -D options with the same name
and different values (and no corresponding -U option)?

  -O  optlevel
    Specify the level of code optimization. If the optlevel
    option-argument is the digit '0' , all special code optimizations
    shall be disabled. [...]

"all special code optimizations shall be disabled" is quite ambiguous,
in particular because optimizations are not clearly defined. Also,
what's "special"?
