#else  // GTEST_HAS_DEATH_TEST

// This macro is used for implementing macros such as
// EXPECT_DEATH_IF_SUPPORTED and ASSERT_DEATH_IF_SUPPORTED on systems where
// death tests are not supported. Those macros must compile on such systems
// iff EXPECT_DEATH and ASSERT_DEATH compile with the same parameters on
// systems that support death tests. This allows one to write such a macro
// on a system that does not support death tests and be sure that it will
// compile on a death-test supporting system.
//
// Parameters:
//   statement -  A statement that a macro such as EXPECT_DEATH would test
//                for program termination. This macro has to make sure this
//                statement is compiled but not executed, to ensure that
//                EXPECT_DEATH_IF_SUPPORTED compiles with a certain
//                parameter iff EXPECT_DEATH compiles with it.
//   regex     -  A regex that a macro such as EXPECT_DEATH would use to test
//                the output of statement.  This parameter has to be
//                compiled but not evaluated by this macro, to ensure that
//                this macro only accepts expressions that a macro such as
//                EXPECT_DEATH would accept.
//   terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
//                and a return statement for ASSERT_DEATH_IF_SUPPORTED.
//                This ensures that ASSERT_DEATH_IF_SUPPORTED will not
//                compile inside functions where ASSERT_DEATH doesn't
//                compile.
//
//  The branch that has an always false condition is used to ensure that
//  statement and regex are compiled (and thus syntactically correct) but
//  never executed. The unreachable code macro protects the terminator
//  statement from generating an 'unreachable code' warning in case
//  statement unconditionally returns or throws. The Message constructor at
//  the end allows the syntax of streaming additional messages into the
//  macro, for compilational compatibility with EXPECT_DEATH/ASSERT_DEATH.
