+The zs serial port driver has been removed from Solaris. The zs specific code
+in the parsolaris.c and parsestreams.c file now fails to compile. This patch
+simply replaces the "ifdef sun" sections of code with a fictious define to
+prevent the zs code from being compiled. The removal of all driver specific
+code has been reported to the community as bug 2988
+(http://bugs.ntp.org/show_bug.cgi?id=2988) This patch may be removed when NTP
+is upgraded to a version that has that bug resolved.
