Ultimately, it makes more sense to use Cygwin's perl with cygwin, rather than a
third-party perl that doesn't understand cygwin.

http://www.gnu.org/software/autoconf/manual/autoconf.html#Shell-Substitutions
which documents how use of ${1+"$@"} works around bugs in older zsh and ksh.
Actually, modern ksh apparently still has a different bug, which it does not
work around:
http://lists.gnu.org/archive/html/automake-patches/2010-02/msg00005.html
so patches to the autoconf manual are welcome. But this is starting to stray
(WAY) off-topic for cygwin.
