As Graham asked, are you building with CMake?  If so, you need to add it to 
LIBWIRESHARK_FILES in epan\CMakeLists.txt.

libwireshark.def isn't present in 1.10, either; 1.10 was, in fact, the release 
in which it disappeared. "The past" must've been with 1.8 or earlier.

Same way as you'd do it in a 1.10 environment or a 1.12 environment - declare 
it in a header file with WS_DLL_PUBLIC and *make sure that the file in which 
it's defined includes that header file* (which is *always* what should be done 
in C-based languages in all versions of all programs, to make sure the 
definition agrees with the declaration).

In a 2.x environment, you also have to make sure the file is in the appropriate 
CMakeLists.txt as well as the appropriate Makefile.common.
