# Find the posix library needed on INTERACTIVE UNIX (ISC)
dnl
dnl From the Autoconf 2.53 manual (AC_ISC_POSIX):
dnl
dnl For INTERACTIVE UNIX (ISC), add `-lcposix' to output variable
dnl `LIBS' if necessary for POSIX facilities. Call this after
dnl `AC_PROG_CC' and before any other macros that use POSIX
dnl interfaces. INTERACTIVE UNIX is no longer sold, and Sun says that
dnl they will drop support for it on 2006-07-23, so this macro is
dnl becoming obsolescent.
dnl
AC_SEARCH_LIBS([strerror], [cposix])
dnl
dnl Autoconf stopped setting $ISC sometime before 2.53
dnl
dnl If this is still important, someone should come up with a generic test
dnl for whether _SYSV3 needs to be defined. Removed code below:
dnl
dnl if test "$ISC" = yes; then
dnl CFLAGS="$CFLAGS -D_SYSV3"
dnl # And I don't like this... In theory it should be found later if server is
dnl # enabled, but maybe something on INTERACTIVE UNIX (ISC) we didn't ask to
dnl # link with crypt tries? Anyhow, the autoconf manual says we can delete
dnl # this ISC stuff on or after 2006-07-23 when Sun discontinues support and
dnl # ISC becomes obsolescent, but I suppose that is probably a matter of
dnl # opinion.
dnl #
dnl # N.B. The reason for doing this is that some moron decided to put a stub
dnl # for crypt in libc that always returns NULL. Without this here, the later
dnl # check will find the stub instead of the real thing, resulting in a server
dnl # that can't process crypted passwords correctly.
dnl
dnl # again, if we have to try and reenable this for ISC, someone should come
dnl # up with a generic test that figures out whether crypt is good or not -
dnl # Is it always returning NULL?
dnl LIBS="-lcrypt $LIBS"
dnl fi
dnl
dnl FIXME - This has been broken for at least a few months anyhow, so I'm
dnl removing the crypt lib define above, but the correct fix would be to
dnl provide a CRYPT_WORKS macro or the like that gets called sometime after
dnl the AC_SEARCH_LIBS call that normally finds crypt, and if crypt doesn't
dnl work, the macro should be retried with LIBS="-lcrypt $LIBS" forced.
