+/* Test for _Bool bit-fields.  After TC2, the width of a _Bool
+   bit-field must not extend the width (number of sign and value bits)
+   of _Bool, which is implementation-defined but is 1 unless the
+   implementation defines representations for values greater than 1 in
+   type _Bool and allows for _Bool objects to have such types, which
+   GCC does not.  */
