        * error.c (SIZE_MAX) [!defined SIZE_MAX]: Define.
        (error_tail): Do not loop, reallocating temporary buffer, since
-       the original size is big enough.  This avoids one potential size
-       overflow calculation.  Check for size overflow when calculating
-       temporary buffer size.  Free temporary buffer when done, if
-       it was allocated with malloc; this closes a memory leak.
+       the output cannot contain more wide characters than the input
+       contains bytes, the size must be big enough already.  This avoids
+       one potential size overflow calculation.  Check for size overflow
+       when calculating temporary buffer size.  Free temporary buffer
+       when done, if it was allocated with malloc; this plugs a memory

+       needed now that we're assuming C89 or better.
 
        Merge error changes from glibc.
