Sorry, I don't know.

Yes, it should say "no".

What is the corresponding log output?  I am looking for the output of
the following fragment in configure.  If the compiler crashed, then
the first "ac_status=$?" quoted below should set ac_status to a
nonzero value.  The next "echo" statement logs that value, so I'd
like to see what it is.

echo "$as_me:$LINENO: checking for stdbool.h that conforms to C99" >&5
echo $ECHO_N "checking for stdbool.h that conforms to C99... $ECHO_C" >&6
if { (eval echo "$as_me:$LINENO: \"$ac_compile\"") >&5
  (eval $ac_compile) 2>&5
  echo "$as_me:$LINENO: \$? = $ac_status" >&5
  (exit $ac_status); } &&
         { ac_try='test -s conftest.$ac_objext'
  { (eval echo "$as_me:$LINENO: \"$ac_try\"") >&5
  (eval $ac_try) 2>&5
  echo "$as_me:$LINENO: \$? = $ac_status" >&5
  (exit $ac_status); }; }; then
  echo "$as_me: failed program was:" >&5
sed 's/^/| /' conftest.$ac_ext >&5
