Ian,
Thanks for clarifying this. I located two logs which I take to be
the 2 stages:
libcpp/config.log
prev-libcpp/config.log
Searching these gave the following.
(I included "exit" in the RE search to clarify how far into the file the
match was found, and to confirm that the RE worked! There is a wc
to confirm the file sizes.)
bash>egrep -n "SSE4|pcmpestri|configure: exit" {,prev-}libcpp/config.log
libcpp/config.log:3567:#define HAVE_SSE4 1
libcpp/config.log:3569:configure: exit 0
prev-libcpp/config.log:3582:#define HAVE_SSE4 1
prev-libcpp/config.log:3584:configure: exit 0
bash>wc -l {,prev-}libcpp/config.log
3569 libcpp/config.log
3584 prev-libcpp/config.log
So pcmpestri was not located.
Thanks,
Ellis

That test
evidently failed with the stage 1 compiler but passed with the stage 2
compiler. Looking at libcpp/config.log in both stage 1 and stage 2
might tell you more. Look for SSE4 or pcmpestri.
