(20070302) Warning messages on FreeBSD 4.11-RELEASE (Re: Call for release testing.)

[Norihiko Murase]

Two kinds of the warning messages were displayed when I
tried building the snapshot 20070302 on the machine where
FreeBSD 4.11-RELEASE is running.

The environment under which I built it is as follows:
    CPU: i386 family
    OS: FreeBSD 4.11-RELEASE
    Compiler: gcc 2.95.4 20020320 [FreeBSD] (/usr/bin/gcc)

The options I specified in executing the configure script are as follows:
./configure --prefix=/usr/local/OpenSSH --datarootdir='$(prefix)' --with-rpath \
  --without-osfsia --with-zlib=/usr/local/zlib --without-skey --with-tcp-wrappers \
  --with-libedit=/usr/local/libedit --without-audit --without-pam \
  --with-ssl-dir=/usr/local/OpenSSL --without-rand-helper \
  --with-privsep-user=sshd --with-privsep-path=/var/empty \
  --without-sectok --without-opensc --without-kerberos5 \
  --with-xauth=/usr/X11R6/bin/xauth --without-ipaddr-display \
  --with-default-path=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin \
  --with-superuser-path=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin \
  --without-4in6 --with-pid-dir=/var/run


The warning messages displayed when I built it are
classified into two:
    (1) warning: `MAXSYMLINKS' redefined
    (2) warning: `__nonnull__' attribute directive ignored
Both kinds of them are displayed
when openssh/openbsd-compat/bsd-misc.c is compiled, just as follows:
------------------------------------------------------------
gcc -g -O2 -Wall -Wpointer-arith -Wuninitialized -Wsign-compare  -I. -I.. -I. -I./.. -I/usr/local/OpenSSL/include -I/usr/l

------------------------------------------------------------


I'm very happy if you give me some comments about this.

Thanks,
