Comment (by dobenour):

 Can we use Language-C?  It is a C parser written in Haskell, and we could
 generate the output from the parse tree.

 Not sure if it can parse everything in `Rts.h`, though.  If there is a
 problem, it would most probably be in the system headers included by
 `Rts.h`, not `Rts.h` itself.
