CVS commit: src/lib/libc/stdio

Modified Files:
        src/lib/libc/stdio: fflush.c

Log Message:
Include the 0 return from write. Although the real write system call does
not return 0, the synthetic writes from funopen/fmemopen could. This avoids
infinite loops in >= test19 in fmemopen, but the tests still fail, perhaps
because they assume the previous behavior, where flush does not adjust the
stdio pointers on error.
