As far as the only task is to extract the file names of all included files
given a set of pp constants (compiler/library/platfrom specific) this is
supported by Wave out of the box. For this to happen I'd propose you create
config files containing the corresponding macro definitions to mimic the
needed compiler etc. For instance for the VC7.1 this would look like:

BTW: There is a sample included in the Wave package, which shows how to use
the include file listing feature (list_includes).
