+ Enable full POSIX signal support, including signal handling,
+ thread cancellation, timers, and process-related notifications.
+
+ This option provides the most complete signal functionality,

+ Disable process-related signal functionality while keeping
+ basic signal handling support.
+
+ This option provides a balance between reduced resource usage
+ and limited signal functionality.
+
+ Typical use cases:
+ - Applications using basic signals without fork/exec
+ - Resource-constrained real-time systems
