@@ -13,8 +13,6 @@ BYTESWAP	Used when compiling for a hardware architecture that has
 		byte-swapped words and word-swapped 32-bit cells, e.g. 80386.
 SYSVSIGNALS	True when compiling on a system that requires the use of
 		SYSV (rather than BSD) signal-handling code.
-SYSVONLY	True when compiling on a system that has little or no
-		BSD support.  E.g. gettimeofday is missing.
 I386		True if compiling for the Sun386i (not just any 80386);
 		used because the 386i's display controller is odd.
 OS4		True if compiling for SunOS 4.x
