+Subject: [PATCH] tests: fix race in aclocal/autoheader calls
+
+Put the sleep 1 after aclocal run, same as autoreconf does.  This
+guarantees that 'aclocal.m4' will have smaller timestamp than
+'config.h.in' and avoids re-running autoheader later on.
+
+* tests/testsuite.at (LT_AT_ACLOCAL): Sleep sec after aclocal run.
