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.
