[boost] boost/pool/pool.hpp why reinterpret_cast instead of static_cast?

Hi,

In the file
https://svn.boost.org/trac/boost/browser/trunk/boost/pool/pool.hpp there's
the following code:

struct default_user_allocator_malloc_free
{

  ...

  static char * malloc(const size_type bytes)
  {
    return reinterpret_cast<char *>(std::malloc(bytes));
  }

  ...

};

It is my understanding that void* to T* convertions should be done using
static_cast and not reinterpret_cast.
Is there a reason for using reinterpret_cast there?

Thanks,
Philippe
