The libstdc++ testsuite has been updated to correctly handle the ibm128 numeric type. Previously, ibm128 (a double-double floating-point format) was incorrectly identified as conforming to IEC 559 standards, causing test failures. This change adjusts the tests to accurately reflect ibm128’s properties.
