i have read that several times,but i find little things.
i also have read the treelang front end.
i just find that:
these two functions of treelang are in gt-c-decl.h.
the file is generated from c-decl.c which is not part of the treelang front end.
so, if i do not include these c front end files in my front end,
what i should do??
