--- Comment #2 from simon at pushface dot org ---
The bug I reported is (from here) still present exactly as reported, for all
documentation releases up to 4.9.3.

At 5.3[1], the RM cunningly works round the original problem by replacing 
the link with plain unlinked text: "see the section on Optimization and 
Strict Aliasing in the GNAT User's Guide."

Somewhat unfortunately, the UG[2] is now generated at gnat_ugn, not 
gnat_ugn_unw, which means that the RM didn’t actually need fixing at all!
