-/* The following macros are supposed to replace calls to _flockfile/_funlockfile
-   and __sfp_lock_acquire/__sfp_lock_release.  In case of multi-threaded
-   environments using pthreads, it's not sufficient to lock the stdio functions
-   against concurrent threads accessing the same data, the locking must also be
-   secured against thread cancellation.
-
-   The below macros have to be used in pairs.  The _newlib_XXX_start macro
-   starts with a opening curly brace, the _newlib_XXX_end macro ends with a
-   closing curly brace, so the start macro and the end macro mark the code
-   start and end of a critical section.  In case the code leaves the critical
-   section before reaching the end of the critical section's code end, use
-   the appropriate _newlib_XXX_exit macro. */
