I'll wait more time than, a review form you is certainly worth more
delay.  Thanks.

Yes (at least, until Autoconf decides that is time to start requiring
a POSIX shell for the configure scripts it generates, and sets
CONFIG_SHELL accordingly ;-)

Our test scripts are not build, but hand-written (OK, some are
automatically generated, but even those are thin layers around other
test scripts, or some '.sh' "driver" that runs most of the actual
checks).  So an use of m4sh is out of question (too much churn and
risks of regression).  Plus, it wouldn't help with many of the most
annoying bugs (i.e., Solaris /bin/sh "optimizing" away every ":"
command after the firs one in a loop, even if they are redirected).
