-// 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.

+// 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.
