Thanks, Karl.  Yes, using autoconf-2.72.

Using am_cv_sleep_fractional_seconds=false dropped it to 7-11 tests failing.  Strangely (to me), it isn't consistent: I've run this 8 times, each in a new fresh download of 1.16j.  The following 7 tests always fail:

* py-compile-basedir -- it fails because I installed Python 3.12, which has removed the "imp" module in favor of the "importlib" module ("imp" was deprecated starting in Python 3.4).

* yacc-bison-skeleton, yacc-d-basic, yacc-deleted-headers, yacc-depend, yacc-depend2, yacc-mix-c-cxx -- these all fail not finding the yyparse function.  Some of the other yacc-.* tests seem to have yyparse in them so it's not immediately clear to me why these 6 consistently fail.

The following failed 3 of 8 times (tests #1 & #3 & (#6 or #8))

* aclocal-deleted-header
* aclocal-deleted-header-aclocal-amflags

The following failed 2 of 8 times (tests #1 & #3)

* aclocal-deps

The following failed on 1 of 8 times (test #1)

* subdir-add2-pr46

Log files for the 11 failed tests are attached, along with a gzip'd test-suite.log
