I have a utility written in Python called stripper which does half of what
you're asking. 

 Usage
 stripper [-f] -k KEYWORD infile1 ... outpath
 
 Parameters
 -f         force clobbering of output files
 -k KEYWORD Remove the text marked by a #define KEYWORD/#endif pair
 infiles    a list of input files. The output files have the same name
            as the input files suffixed with a ".fixed".
 outpath    path to where the files should be written. If no
            directory is specified, then the current directory is
            used.

It will remove any blocks of code which are defined by a define/endif pair.
It doesn't handle elses nor elifs (because it was written to solve a particular
problem). It should be easy to change to suit your purposes (although
it is not especially well-written). If you think that you may find it useful
then I'll send it to you.

Cheers,

Mark
