An issue about secondary allowed data type in function parser_datatype_is_secondary_allowed_for_type().

bool parser_datatype_is_secondary_allowed_for_type(const char* type)
{
    return S_EQ(type, "long") //i.e long int, long long
      || S_EQ(type, "short"); //short int
      || S_EQ(type, "double") //????
      || S_EQ(type, "float"); //????
}

double and float shouldn't be here.
