Sounds hopeful, if BRACED_CODE is the ordinary code one wants to  
place. :-)

I think though the syntax should, for user readability, include
  %define KEY {VALUE}
where KEY is a standard C-label, or whatever Bison is normally is  
using. The STRING version should then be there in cases, this non- 
quoted version does not suffice. So one should be able to write:
%define header_code {
  ...
}
and so on, without quotes, or if Bison accepts it in other similar  
places,
%define header-code {
  ...
}
with a "-" instead of the silly "_".
