-  dnl The AC_SEARCH_LIBS call is a hack to persuade the Solaris 8 linker to
-  dnl find inet_ntop.

-  dnl It is the responsibility of gl_INET_NTOP's caller to arrange for
-  dnl -lnsl if it is needed.  Normally -lnsl is not needed on Solaris 8,
-  dnl since inet_ntop is needed only by getaddrinfo, and getaddrinfo
-  dnl isn't built on Solaris 8.
+  dnl Most platforms that provide inet_ntop define it in libc.
+  dnl Solaris 8..10 provide inet_ntop in libnsl instead.
