@item --enable-vtable-verify
Specify whether to enable or disable the vtable verification feature.
Enabling this feature causes libstdc++ to be built with its virtual calls
in verifiable mode. This means that, when linked with libvtv, every
virtual call in libstdc++ will verify the vtable pointer through which the
call will be made before actually making the call. If not linked with libvtv,
the verifier will call stub functions (in libstdc++ itself) and do nothing.
If vtable verification is disabled, then libstdc++ is not built with its
virtual calls in verifiable mode at all. However the libvtv library will
still be built (see @option{--disable-libvtv} to turn off building libvtv).
@option{--disable-vtable-verify} is the default.

* Makefile.am: Remove #if ENABLE_VTABLE_VERIFY checks around
definitions of SUBDIRS, libvtv_la_SOURCES and libvtv_include_HEADERS.
* Makefile.in: Regenerate.
