+ * with picky compilers like Clang 8 and 9. Since we use Clang for the
+ * find-all-the-warnings case, switch those warnings off for
+ * the we-can't-change-them system headers.
+ *
+ * This convenience header handles including all the bits we need for
+ * Python support, while silencing warnings.
