--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Make gengtype wrap the output in

#ifndef GENGTYPE_DEFINED_<type>
#define GENGTYPE_DEFINED_<type>
...
#endif

so any duplicate gets weed out by the preprocessor ;)

gengtype is just a not very up to the task of GCC being written in C++ now ...
