+@node Legacy Function Substitutes
+@chapter Past POSIX Function Substitutes
+
+This chapter describes which functions and function-like macros specified by
+older versions of POSIX (POSIX:2001) are substituted by Gnulib, which
+portability pitfalls are fixed by Gnulib, and which (known) portability
+problems are not worked around by Gnulib.
