Just trying to understand why there is a difference between:

extern gcc_jit_struct *
gcc_jit_context_new_struct_type (gcc_jit_context *ctxt,
gcc_jit_location *loc,
const char *name,
int num_fields,
gcc_jit_field **fields);

/* Unions work similarly to structs.  */
extern gcc_jit_type *
gcc_jit_context_new_union_type (gcc_jit_context *ctxt,
gcc_jit_location *loc,
const char *name,
int num_fields,
gcc_jit_field **fields);
