There is no portable way to do an "is this a socket?" test - there are
quite a number of systems that do not have unix sockets, and thus no way
to do "test -S".

One *could* do something like 

  if test -f $socket
  then
      if [ "`ls -l $socket | cut -c1`" = "s" ] ; then
	   echo "socket found"
      fi
  fi

but that's ugly as hell (and I'm sure it's not portable to some other
system).

Hmmm.  One could run a test program in C to see "is this a socket, and
is there egd running on it", that would be even better...

Thanks.

I can't say for sure - last time I tried this on SCO 3.0, I got lots of
warnings as well, but didn't really care to sort out which ones are
"configure" related and which ones are just SCO weirdness.

Hmm.

2.7.2.3.  But actually it's the assembler choking on something GCC
produced.

Maybe this is just something for the FAQ - "if you see an error like this
on SCO, compile the offending module without '-g'".

Interesting enough, it *was* compiled into libopenbsd-compat.a, at least
it shows up in "nm":

$ nm openbsd-compat/libopenbsd-compat.a |grep utimes
utimes              |      68|extern|            int( )|    34|     |.text

Nevertheless it's not found when linking - this is weird.

AH!!  From an old run, I had an "libopenbsd-compat.a" lying around in the
main build directory, and the link stage is done with "-L.  -Lopenbsd-compat",
so it was linking the old and stale one.  Removed that, utimes() issue
solved, scp links fine.

"make clean" didn't remove the old library, 'cause the Makefile was already 
upgraded, and forgot everything about ./libopenbsd-compat.a ...

So I should have done 

   make clean
   cvs update -d
   autoheader
   autoconf
   ./configure

- noted, for the next time.
