The current version of the code is getting warnings such as
../../epan/tvbuff.c:54:29: error: uninitialized const 'tvb_real_ops' is invalid
in C++ [-Werror=c++-compat]
../../epan/tvbuff.c:55:29: error: uninitialized const 'tvb_subset_ops' is
invalid in C++ [-Werror=c++-compat]
../../epan/tvbuff.c:56:29: error: uninitialized const 'tvb_composite_ops' is
invalid in C++ [-Werror=c++-compat]
../../epan/tvbuff.c:3666:29: error: duplicate declaration of 'tvb_real_ops' is

I assume the intent of the lines around line 54-56 is that they be forward

in C++:
