Hi Aldy,
Here are the things I found with the patch. All my comments have
"BVI:" in front of them.
BTW, it would be nice if you could use standard mailer quotation when
responding (">", etc).

BVI: I am OK with removing this return, but the reason why I put it there is
because it gets easier for me to set the break point there.
This is not standard practice in GCC source code. It will have to be
removed if we ever merge.

BVI: This is incorrect. #pragma grainsize is part of cilk keywords. It has no
relation to the pragma simd and it will work wthout vectorization support.
Fixed, let me know if the current implementation is correct.

BVI: I am in the process of doing so. I will send out that patch as soon as I
get some free time.
Ok, I have left all the FIXMEs so we don't miss any of them.

BVI: Are you sure the compiler let you get away this this? It gave me a warning
once (in stage2 I believe).
Sure, I've done it for years.
BVI: I have fixed these scripts already: the correct notation that I have used is
"cilkplus_<type>_<language>_<compile/execute/errors>.exp
Ok, I have removed them from my patch.

BVI: Why did you replace a space with a tab?
Whoops, removed the space (and the tab).
How about this?
