It's the compiler vendors that determine which predefined symbols
will be present.  The latest Sun compilers define __SVR4.

However, I believe that using the system type to determine which features
to select wrong.  The method you should use should be like GNU's
autoconf.  For each feature you want, use a feature test macro.
This also gives users the flexibility to determine whether to use
terminfo or termcap (when both are present), instead of being forced
to use termcap because that's what the implementer though you
should use on SunOS 4.
