Hi,

Sorry I'm late.

I copied a patch part from ltp-list and apply it, but the patch failed.
I didn't notice that tabs in the patch were changed to blanks,
and I took time. Forgive me.

But, I could make right patch by copying from your email, and I succeeded. 

As a result, mbind01 became PASS by applying your last patch. 


Thank you.

    Ok -- that makes more sense.. besides, I think gcc was optimizing
out the first branch with -O2 if it always evaluated to false. Here's
the new patch (I'm keeping the errno = ENOSYS part because I want to
make sure that tst_brkm doesn't mess up the errno value if a write(2)
fails or something).
Thanks!
