textutils-2.1 configure error

[TenThumbs]

On my Linux system I said ./configure and it said
  checking for working long double with more range or precision \
  than double... no
which is wrong. Looking at configure I find the test

#include "confdefs.h"
#include <float.h>
          long double foo = 0.0;
int
main ()
{
static int test_array [1 - 2 * !(/* Using '|' rather than '||' catches a
GCC 2.95.2 x86 bug.  */
          (DBL_MAX < LDBL_MAX) | (LDBL_EPSILON < DBL_EPSILON)
          | (DBL_MAX_EXP < LDBL_MAX_EXP) | (DBL_MANT_DIG <
LDBL_MANT_DIG))];
test_array [0] = 0

  ;
  return 0;
}

It turns out that for gcc 2.95 or lower the compiler returns the error:
   storage size of `test_array' isn't constant
so this test is actually a test for gcc 3 and above despite what the
comment implies and what its description says.

Obviously a bug in the autoconf you used.

Thanks.
