If you use cpphs as a library, there is an API called runCpphsReturningSymTab. Thence you can throw away the actual pre-preprocessed result text, keep only the symbol table, and lookup whatever macros you wish to find their values. I suggest you make this into a little code-generator, to produce a Haskell module containing the values you need.
