In stock VM I noted the plugin are not stripped. Does it make sens to strip the plugin, and if so how can it be inserted in the arcane of the Squeak-vm configuration script?

I remember about the -s linker option, but it may break the dynamic linkage, right?

I was looking into the same topic a few weeks ago. The two papers linked below are very useful and make a clear case for stripping symbols for several reasons, some not so obvious.

Also if the VM build used the "-fvisibility=hidden" compiler option and plugin devs used the following macro for explicitly exports then plugins would be leaner, safer and closer to compiling on Windows (a more comprehensive solution at [3]).

#define DLLEXPORT __attribute__((visibility ("default")))
