+   which defines a macro called FILE_TYPE that breaks "tree.h".
+   Fortunately it uses #ifndef to suppress multiple inclusions.
+   Three possible cases:
+       1) <stdio.h> has already been included -- ours will be no-op;
+       2) <stdio.h> will be included after us -- "theirs" will be no-op;
+       3) <stdio.h> isn't needed -- including it here shouldn't hurt.
+   In all three cases, the problem macro will be removed here.  */
