Update to 1.4.3.1
> ####################### V 1.4.3.1:
>
> corrections:
>         PROBLEM: UNIX socket listen accepted only one (or a few) connections.
>         FIX: do not remove listening UNIX socket in child process
>
>         PROBLEM: SIGSEGV when TCP part of SSL connect failed
>         FIX: check ssl pointer before calling SSH_shutdown
>
>         In debug mode, show connect client port even when connect fails
>
> ####################### V 1.4.3.0:
>
> new features:
>         socat options -L, -W for application level locking
>
>         options "lockfile", "waitlock" for address \ 
level locking
>         (Stefan Luethje)

>         option "readbytes" limits read length (Adam Osuchowski)

>         pty symlink, unix listen socket, and named pipe are per default removed
>         after use; option unlink-close overrides this new behaviour and also
>         controls removal of other socat generated files (Stefan Luethje)
>
> corrections:
>         option "retry" did not work with tcp-listen
>
>         EPIPE condition could result in a 100% CPU loop
>
> further changes:
>         support systems without SHUT_RD etc.
>         handle more size_t types
>         try to find makedepend options with gcc 3 (richard/OpenMacNews)
