You might want to use comments on #else and #endif to make it a bit easier to figure out what #else is the opposite of and what #endif terminates.

"Work" as in "not fail to compile", or "work" as in "keep symbols from being exported outside the library if not marked as being exported by the library"?

At least some UN*X compilers might support GCC-style __attribute__(visibility(...)) options, but I don't know whether all the ones that would be used to compile Wireshark, on platforms where the linker can hide symbols, do.
