You are given a code snippet that shows the destructor of a class called `pb2bv_model_converter`. The destructor is responsible for releasing the resources held by the class.

In the provided code snippet, `m_c2bit` is a member variable of type `svector` (an STL-like vector) that stores `func_decl_pair` elements. A `func_decl_pair` consists of two pointers to `func_decl` objects, named `first` and `second`.

The destructor iterates over the elements in `m_c2bit` and calls `m.dec_ref` on both `first` and `second` to decrement their reference counts.

Your task is to implement a function that accomplishes the same functionality as the destructor described in the given code snippet.

Write a function:
```cpp
void release_resources(svector<func_decl_pair>& c2bit);
```

**Input**
- `c2bit` (1 <= `c2bit.size()` <= 10^6): A reference to an `svector` of `func_decl_pair` elements. Each `func_decl_pair` consists of two pointers to `func_decl` objects.

**Output**
- None. The function should modify the input vector `c2bit` to release the resources.

Note that it is sufficient to decrement the reference counts of `first` and `second` and not remove the corresponding elements from `m_c2bit`.

**Constraints**
- The `func_decl` objects are already allocated and have valid pointers.

Sure, I can help you implement the `release_resources` function based on the given code snippet. Here's how it could be done in C++:

```cpp
void release_resources(svector<func_decl_pair>& c2bit) {
    for (const auto& pair : c2bit) {
        pair.first->dec_ref();
        pair.second->dec_ref();
    }
}
```

This function uses a `const auto&` here because we don't need the mutable reference to modify the original vector's elements. We're only accessing the `first` and `second` member variables of each `func_decl_pair` to decrement their reference counts using the `dec_ref()` function.

Sure, here's a function that accomplishes the same functionality as the destructor described in the given code snippet:

```cpp
void release_resources(svector<func_decl_pair>& c2bit) {
    for(auto& pair : c2bit) {
        pair.first->dec_ref();
        pair.second->dec_ref();
    }
}
```

This function iterates over each `func_decl_pair` in the `c2bit` vector. For each pair, it calls the `dec_ref()` function on both the `first` and `second` pointers to decrement their reference counts. This is the same functionality as described in the destructor of the `pb2bv_model_converter` class.
