The files are indeed cleaned at the end of the configure script.

address@hidden [testsuite.dir/156]> ./configure
[...]
+ test 0 != 0
+ echo configure: exit 0
+ rm -f core *.core
+ rm -f -r conftest.in conftest.nl conftest.out confdefs.h conf23761*
+ exit 0
address@hidden [testsuite.dir/156]> 

But the autotest framework add some extra hooks (AC_STATE_SAVE) in the
configure.ac:

address@hidden [testsuite.dir/156]> cat configure.ac 
AC_INIT
AC_CONFIG_AUX_DIR($top_srcdir/config)
AC_CONFIG_HEADER(config.h:config.hin)
AC_PROG_GREP
AC_STATE_SAVE(before)
AC_PROG_SED
AC_OUTPUT
AC_STATE_SAVE(after)

This way it checks that autoconf macros do not forget to clean
temporary files they create.
