I had left the removal of unneeded subshells (which would indeed jump up
when the code is moved to shell functions) for later.  But since you're
at it this one:

>   (exit $ac_status); }])

in _AC_RUN_LOG_STDERR and _AC_RUN_LOG could also be changed to an
ac_func_set_status shell function that does just "return $1".  A
candidate for m4sh maybe?

Or possibly it can also be replaced simply with "test $ac_status != 0",
avoiding the zsh bug (even though anyway the buggy shells will be
skipped by the better-shell test).
