 Is there any way to fix this, or is it not possible?
 (This comes from generated code. Idiomatic C would use a T* here rather than T(*)[], but that is not an option. Other compilers like tcc, DMC and mine have no problem with it.)

Clang says: definition of 'struct scenet' is not complete until the closing '}'
Can you loose the parens? 'struct scenet *child[];' is fine (so long as it's the last element).
Otherwise, 'struct scenet **child;' or 'struct scenet *child' - depending on whether you mean 'children' or 'next';
