Felix,

I understand that you are no longer interested in.

Anyhow the mkgmap source code contains a SubstitutionFilter class which 
performs some string replacements. This should work to replace and to 
remove common words.

I don't know how this filter can be configured in the style file but 
maybe someone else remembers.
