I am pretty sure that is not the way to do it in sparse.  If you just want
add some sparse builtin defines, it is much better to add them in
create_builtin_streams(). It would be even better to group them in a new
function create_builtin_define():

Some thing like:

add_pre_buffer("#weak_define __INT_MAX__ %d\n", __INT_MAX__);
