+Subject: [PATCH] Fix testsuite failures with bash 5.2.
+
+Bash v5.2 includes several new optimizations to the number of
+subshells used for various constructs; as a side effect, the value of
+SHLVL is less stable than it used to be.  Add SHLVL to the list of
+built-in shell variables with unstable values, to be ignored when
+checking for inappropriate differences to the shell environment
+before and after a macro invocation / between two configure runs.
+
+Problem and solution reported by Xi Ruoyao in
+https://lists.gnu.org/archive/html/autoconf/2022-09/msg00015.html
+Problem also reported by Bruce Dubbs in
+https://lists.gnu.org/archive/html/bug-autoconf/2022-09/msg00010.html
+
+* tests/local.at (_AT_CHECK_ENV, AT_CONFIG_CMP): Ignore changes in
+  value of SHLVL.
