+ * stdio-common/tmpnam_r.c: Likewise.
+ * stdio-common/tempnam.c: Add 1 as new parameter to __path_search.
+ * sysdeps/posix/tempname.c: Add new parameter. If value is nonzero
+ consider TMPDIR environment variable and dir parameter. Otherwise not.
+ * stdio-common/Makefile (tests): Add tst-tmpnam.
+ * stdio-common/tst-tmpnam.c: New file.
