glibc-2.4 __stack_chk_guard/__pointer_chk_guard

[Peter S. Mazinger]

Hello!

Both __stack_chk_guard/__pointer_chk_guard are exported unconditionally 
(elf/Versions), but they are guarded w/ #ifndef 
THREAD_SET_STACK_GUARD/THREAD_SET_POINTER_GUARD in elf/rtld.c and 
csu/libc-start.c.

What is the correct approach?
1. Guard them in elf/Versions.
2. Define them unconditionally in the mentioned .c files.

Thanks, Peter

P.S. Please CC me.
