But how does one do it in a shell that doesn't have PIPESTATUS? I know that autoconf (tool to install source on almost Unix that has lots of shell-independent logic in it) plays tricks with redirection and subshells to capture the return values from inner pipe commands. I just never took the time to reverse engineer it in my head to understand it.

Anyone?
