Normally, the linker will add a DT_NEEDED tag for each dynamic library mentioned on the command line, regardless of whether the library is actually needed. `--as-needed' causes DT_NEEDED tags to only be emitted for libraries that satisfy some symbol reference from regular objects which is undefined at the point that the library was linked. `--no-as-needed' restores the default behaviour. Собсно, в первом случае в момент линковки libz нет ссылок на символы оттуда, во втором они появляются. Это уже неоднократно здесь обсуждалось. -- Regards, Sir Raorn.
