I'm not sure I understand the full circumstances, but perhaps it's the
dodgy word splitting in zsh described in the autoconf manual "Shell
Substitutions".

I encountered a problem with this construct on an ancient bash
recently too, where ${1+"$@"} came out as an empty argument, rather
than nothing (the same as "$@" is well-known to do).

Autoconf suggests testing $#,

          case $# in
          0) something ;;
          *) something "$@";;
          esac
