Ah, I see. Sorry, I misunderstood you there. The test is for the type
size_t. I attached the full config.log of dune-common. It seems that
in case of failing test there is simply a #define size_t unsigned int.
Sth that shouldn't have the whole thing failing?!


The relevant parts of configure are (in my case lines 27643ff)

ac_fn_c_check_type "$LINENO" "size_t" "ac_cv_type_size_t"
"$ac_includes_default"
if test "x$ac_cv_type_size_t" = xyes; then :

else

cat >>confdefs.h <<_ACEOF
#define size_t unsigned int
_ACEOF

fi


and (lines 2427ff)


# ac_fn_c_check_type LINENO TYPE VAR INCLUDES
# -------------------------------------------
# Tests whether TYPE exists after having included INCLUDES, setting cache
# variable VAR accordingly.
ac_fn_c_check_type ()
{
  as_lineno=${as_lineno-"$1"}
as_lineno_stack=as_lineno_stack=$as_lineno_stack
  { $as_echo "$as_me:${as_lineno-$LINENO}: checking for $2" >&5
$as_echo_n "checking for $2... " >&6; }
if eval \${$3+:} false; then :
  $as_echo_n "(cached) " >&6
else
  eval "$3=no"
  cat confdefs.h - <<_ACEOF >conftest.$ac_ext
/* end confdefs.h.  */

#ifndef FC_DUMMY_MAIN_EQ_F77
#  ifdef __cplusplus
     extern "C"
#  endif
   int FC_DUMMY_MAIN() { return 1; }
#endif
#endif
int
main ()
{

	 return 0;

  return 0;
}
