+// 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.
