warnings building openssh-3.0.2p1 on HP-UX 10.20

[Albert Lunde]

I'm getting a number of compiler warnings about type mismatches, 
building openssh-3.0.2p1 on HP-UX 10.20 with the HP ANSI C compiler.

The resulting code seems to work, but spot-checking suggested that 
some of the warnings are the result of mixing int and u_int types, 
which might introduce subtle bugs.

I figured it might be worth reporting, since I'm in the minority of 
people not using a gcc-derived compiler, and thus may see different 
errors.  I'm quoting a small section here, I'd be glad to send more 
details to anyone wanting to look into this further.

(This is HP-UX 10.20 with quite a few patches, but not absolutely the 
latest of everything.)

I'm not subscribed to this list, so CC me on replies.

This is the options I used to run configure:

- - cut here - -
#!/usr/bin/csh -vx
rm -f config.cache
setenv CC "cc"
setenv CFLAGS "-Ae +O2 -I/usr/local/include  -I/nuinfo/local/openssl/include"
setenv LFLAGS "-L/usr/local/lib -L/opt/local/openssl"
nohup sh ./configure  --prefix=/nuinfo/local/openssh \
        --sysconfdir=/etc/openssh \
        --with-ssl-dir=/nuinfo/local/openssl/lib        \
        --with-prngd-socket=/var/run/egd-pool   \
        --without-lastlog       \
        --with-cflags="-Ae -I/usr/local/include -I/nuinfo/local/openssl/include"
\
        --with-lflags="-L/usr/local/lib -L/nuinfo/local/openssl" \
        --with-tcp-wrappers \
        --with-ipv4-default \
        --with-default-path="/usr/bin:/usr/contrib/bin/opt/local/bin:"  \
   >& my.configure.out.$$ &

#
echo my.configure.out.$$
#
ps -f

A sample of errors:

(I think, based on a prior version, the first warning about "stat" can be fixed by commenting out "struct stat;" in openbsd-compat/glob.h I'm more worried by the other errors.)
