/* The following macros improve performance of the stdio by reducing the
number of calls to _bufsync and _wrtchk. _BUFSYNC has the same
effect as _bufsync, and _WRTCHK has the same effect as _wrtchk,
but often these functions have no effect, and in those cases the
macros avoid the expense of calling the functions. */
