I might suggest using the Eli compiler construction toolset. An ANSI C
specification already exists for it and it includes an unparsing tool
that will allow you to recreate the input with your modifications. In
Eli, you would use attribute grammar computations to specify how you
want to change the output.


I have written a source-to-source C translator that does something
similar in Eli and manages to preserve things like comments to make
your output more readable.


More information about Eli can be found at
