/* These are wrappers for functions/macros from the GNU C library, and

   from other C libraries supporting POSIX's optional thread-safe functions.

   The standard I/O functions are thread-safe.  These *_unlocked ones are

   more efficient but not thread-safe.  That they're not thread-safe is

   fine since all of the applications in this package are single threaded.

   Also, some code that is shared with the GNU C library may invoke

   the *_unlocked functions directly.  On hosts that lack those

   functions, invoke the non-thread-safe versions instead.  */
