Indeed.

According to the OpenGroup that syntax should be fine:

as a workaround?

It works for me under Solaris 10. Perhaps Solaris 9 or older do not have a standard compliant /bin/sh program. What do you suggest we use instead

    #! /bin/sh
    if ${1+"$@"}; then
        exit 1
    else
        exit 0
    fi
.)

For backward compatibility reasons sh in Solaris 9 and earlier is not POSIX compliant. Use /usr/xpg4/bin/sh or /bin/bash instead. (Unfortunately you can't cheat and define a shell function, although you could create a program called "!":
