+# @LOCALMOD-START The PNaCl driver automatically adds dependencies to
+#                 libc++ which hasn't been built yet. The tests for
+#                 flags therefore fail because the library can't be
+#                 found. We should fix this in a different CL, and add
+#                 proper detection for newlib's lack of locale_t
+#                 support. See:
+#                  https://code.google.com/p/nativeclient/issues/detail?id=3661
