-              The test appears to test that division by zero is
-              detected by Boost.Test. This is not happening on
-              Darwin, for unknown reasons.
+              The test verifies that Boost.Test detects division by
+              zero. Division by zero has an undefined result 
+              on PowerPC processors. The compiler has to emit extra 
+              code to assert that the divisor isn't zero. 
+
+              Compiler options -fno-trapping-math and -fnon-call-exceptions 
+              might affect this. However, in default configuration
+              no check is done, and division by zero is not detected.
