What is the difference between SIGCLD and SIGCHLD signals?

I want to know what is the basic difference between SIGCLD and SIGCHLD signals? Are these just different names for the same signal on different architectures?

Today, it's an alias, the exact system signal. Fact is, SIGCLD was the System V name for the today, SIGCHLD.

Historically, SIGCHLD originated on BSD and was the name adopted by POSIX. Based on System V SIGCLD the only differences happens when the signal is set to SIG_IGN:

BSD would generate zombies, System-V wouldn't.
