Does it ensure that plugins use only exported APIs on, for example:
HP-UX, if Wireshark itself is compiled with aCC (as would be the case if the user got Wireshark from the HP-UX Porting and Archive Centre);
AIX, if Wireshark itself is compiled with XLC?
Sun Studio 8 through Sun^WOracle Solaris Studio 12 appear to support __hidden as a way of saying "not visible outside the library", __global as a way of saying "visible outside the library and references from within the library could bind to code in the application if the application defines it", and "-xldscope=hidden" to make __hidden the default, so that __global overrides it. That sounds as if it'd be what we'd want. It requires us to tweak compiler options when building libraries, but, well, any build-and-configuration tools that can't handle that are toys....
