[Bug middle-end/33559] GCC manual documents Wstack-protector option but not fstack-protector/fno-stack-protector

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

They are included as far as I can tell:
@item -fstack-protector
Emit extra code to check for buffer overflows, such as stack smashing
attacks.  This is done by adding a guard variable to functions with
vulnerable objects.  This includes functions that call alloca, and
functions with buffers larger than 8 bytes.  The guards are initialized
when a function is entered and then checked when the function exits.
If a guard check fails, an error message is printed and the program exits.

@item -fstack-protector-all
Like @option{-fstack-protector} except that all functions are protected.

They are documented
http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Optimize-Options.html#Optimize-Options

Though I see they are not part of the option index.
