+/* Suppress use of exceptions and rounding modes here to avoid build
+   errors if the FE_* macros aren't defined.
+
+   We intentionally ignore the "exception" arguments of functions that
+   take an exception, since we can't even evaluate the argument
+   without causing a build failure.  The extra level of statement
+   expression wrapping avoids "statement with no effect" warnings.
+   Since the callers don't check for errors anyway, we just claim
+   success in every case.
+
+   The overrides for libc_ functions must happen before we include
+   the generic math_private.h, and the overrides for regular
+   <fenv.h> functions must happen afterwards, to avoid clashing with
+   the declarations of those functions.  */
