The files IEEE_ARITHMETIC.f90 and IEEE_tests_gfortran.f90 must be compiled with the -fno-range-check option (for the second file it triggers PR58027). On x86_64-apple-darwin10 the output differs from the one in 'list': --- tmp 2013-07-30 12:33:24.000000000 +0200 +++ list 2013-07-25 21:27:02.000000000 +0200 @@ -77,7 +77,7 @@ Double precision rounding mode IEEE_DOWN for \pi ~= 3.142 is < value with IEEE_UP. - Double precision rounding mode IEEE_DOWN for \pi ~= 3.141 agrees with IEEE_TO_ZERO. + Double precision rounding mode IEEE_DOWN for \pi ~= 3.142 agrees with IEEE_TO_ZERO.
