                         check that all divisions by 0 have been protected
                         in the tests (so that tests can pass on platforms
                         where the floating-point division by 0 fails).
++ MPFR_TESTS_FPE_TRAP:  Define to trap the FE_DIVBYZERO and FE_INVALID
+                        exceptions; MPFR_TESTS_FPE_DIV needs to be defined
+                        too, and MPFR_ERRDIVZERO should be defined as well
+                        to avoid spurious traps (see above).
 + MPFR_TESTS_TIMEOUT:   Define to enable timeout in the tests. Its value
                         contains the default timeout (in seconds), or 0
                         for no timeout by default, and can be overridden
