+/* This is allowed, with the effect that the 'extern' declaration at block
+   scope refers to the same object as the 'static' declaration at file scope.
+
+      C90 6.1.2.2 [as corrected by TC1], C99 6.2.2:
+
+	  For an identifier declared with the storage-class specifier
+	  extern in a scope in which a prior declaration of that
+	  identifier is visible, if the prior declaration specifies
+	  internal or external linkage, the linkage of the identifier at
+	  the later daclaration is the same as the linkage specified at
+	  the prior declaration.  If no prior declaration is visible,
+	  or if the prior declaration specifies no linkage, then the
+	  identifer has external linkage.
+
+   This is PR 14366.  */
