[Sorry for the belated reply. I just noticed the message below because I
saw it in a web archive. Please, Cc: replies to me, since I am not

>From inspecting the autoconf sources, the problem appears to be in
lib/autoconf/general.m4, not tests/mktests.sh, more precisely in the excerpt
below:
if test -n "$ac_init_help"; then
m4_ifset([AC_PACKAGE_STRING],
[ case $ac_init_help in
short | recursive ) echo "Configuration of AC_PACKAGE_STRING:";;
esac])
cat <<\_ACEOF
m4_divert_pop([HELP_ENABLE])dnl
m4_divert_push([HELP_END])dnl
m4_ifset([AC_PACKAGE_BUGREPORT], [
Report bugs to <AC_PACKAGE_BUGREPORT>.])
_ACEOF
fi
I still do not understand why the quoting of _ACEOF is necessary. Could an
autoconf developer explain it to me, please?
