Hi Pawel,
I'm still having trouble getting this patch to apply, I'm not sure whether
it is the format=flowed in your mail headers, or the quoted-printable
encoding, or something else. Certainly when I open your emails I see :
if (where == vect_body && stmt_info && stmt_in_inner_loop_p
(stmt_info))
The content of the patch is OK to commit, but it would be good to
have a copy on list that can be easily applied.
Thanks,
James
