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.
