+/* This file defines the following macros for accessing a small fixed
+   set of thread-specific `void *' data used only internally by libc.
+
+   __libc_tsd_define(CLASS, KEY)	-- Define or declare a `void *' datum
+   					   for KEY.  CLASS can be `static' for
+					   keys used in only one source file,
+					   empty for global definitions, or
+					   `extern' for global declarations.
+   __libc_tsd_get(KEY)			-- Return the `void *' datum for KEY.
+   __libc_tsd_set(KEY, VALUE)		-- Set the datum for KEY to VALUE.
+
+   The set of available KEY's will usually be provided as an enum,
+   and contains (at least):
+		_LIBC_TSD_KEY_MALLOC
+		_LIBC_TSD_KEY_DL_ERROR
+   All uses must be the literal _LIBC_TSD_* name in the __libc_tsd_* macros.
+   Some implementations may not provide any enum at all and instead
+   using string pasting in the macros.  */
+
+/* This is the generic/stub implementation for wholly single-threaded
+   systems.  We don't define an enum for the possible key values, because
