-@vindex sys_siglist
-Some systems do provide this variable, but with a different name such
-as @code{_sys_siglist}.  On these systems, you can define

-Autoconf normally defines @code{SYS_SIGLIST_DECLARED} when it finds a

-However, when you define @code{sys_siglist} to a different name
-autoconf will not automatically define @code{SYS_SIGLIST_DECLARED}.
