Suggest:
* Source fortification (_FORTIFY_SOURCE) level 3 is now available for applications
compiling with glibc and gcc 12 and later. Level 3 leverages __builtin_dynamic_object_size()
to deliver additional fortification balanced against additional runtime cost (checking
non-constant bounds).
Please post v2.

Carlos, may I push this? This is pretty much exactly what you suggested
with Andreas' suggestion incorporated.
Thanks,
