Is creating a separate static library actually necessary? What would<br>
the results be if those binaries were linked to the static version of<br>
libshared that we already provide support for? I hope the compiler<br>
would be able to drop any unused objects and achieve the same size,<br>
without having to maintain yet another list of files.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">I'd have to recheck, but that was my first idea and didn't pan out (at least with the flags we use for the debian package).</div></div></blockquote><div><br></div><div>It appears I messed up earlier.
