@item --without-symbol-versions
Enables or disables the display of symbol version information. The
version string is displayed as a suffix to the symbol name, preceded
by an @@ character. For example @samp{foo@@VER_1}. If the version is
the default version to be used when resolving unversioned references
to the symbol then it is displayed as a suffix preceded by two @@
characters. For example @samp{foo@@@@VER_2}. By default, symbol
version information is displayed.
