+    Use __builtin___stpncpy_chk when available
+    
+    The builtin has been available in gcc since 4.7.0 and in clang since
+    2.6.  This fixes stpncpy fortification with clang since it does a
+    better job of plugging in __stpncpy_chk in the right place than the
+    header hackery.
+    
+    This has been tested by building and running all tests with gcc 10.2.1
+    and also with clang tip as of a few days ago (just the tests in debug/
+    since running all tests don't work with clang at the moment) to make
+    sure that both compilers pass the stpncpy tests.
