As a nice hint: The new Bourne Shell compiles and runs on Cygwin (thanks to no

This sounds great. How does its performance compare with 'dash'?
Are the various issues described in the GNU Autoconf portability notes
(http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Portable-Shell.html#Portable-Shell)
avoided/fixed by this shell? SunOS's stagnant /bin/sh has been a
continuing issue with POSIX shell script portability. As a result,
Autoconf configure scripts typically elect to re-run themselves with
bash (the World's Slowest Shell) on Solaris sytems. If this shell is
indeed good enough for Autoconf configure scripts, then it would be
good to submit an Autoconf patch so that future configure scripts know
how to detect and use it.
