That would set ident_start to zero even when GCC warnings are disabled, which 
would be a bit slower since ident_start does not need to be initialized. 
Unfortunately there is no syntax in C for a no-op initializer, so there's no way 
to define UNUSED so that it initializes ident_start when GCC warnings are 
enabled and leaves ident_start uninitialized otherwise.
