Log:
Add -Wl,-single_module to the linker flags in Darwin. The page at
http://developer.apple.com/releasenotes/DeveloperTools/RN-dyld/index.html
says
The static linker ld(1) supports building dylibs as either
-multi_module or -single_module. Conceptually, a multi-module
dylib is like a group of smaller dylibs - one per source file.
The extra meta-data in a multi-module dylib allowed (pre-10.4)
dyld to delay binding and running initializers on the individual
modules. In Mac OS X 10.4 dyld ignores all multi-module
meta-data and completely binds and runs all initializers the
same as if it were built single-module. In general, building
dylibs -single_module is preferred. The one case where
multi-module is still useful is it allows internal functions of
a dylib to be interposable. For instance, libSystem.dylib is
built multi_module so that malloc() can be overridden and all
uses of malloc in libSystem (e.g. strdup) would be redirected
to use the overridden version.
and we don't need the interposability for our dylibs, and Andreas Fink
indicates that it's necessary for the packaged Wireshark builds he's
doing.
