I just tested on OpenBSD 4.7, FreeBSD 8.1, and MirBSD 10; that reports
failure for all three of those distros.  However, it also reports
failure for dash and latest dash.git, as well as pdksh.  So the
bug is pretty much inherited by all ash derivatives.

It passes on bash, zsh, Solaris /bin/sh, and ksh93.

Additionally, Autoconf should probably document this bug.
