We're aware of these -- they're an artifact of the configure
process. But they should be harmless.

If this is from b31, I wouldn't focus much on the wrapper compiler
flag changes -- I think the other changes that we made are what made
it work. If you still care, you can try compiling manually with the
same options that you had before -- I'm *guessing* that it should
still work fine and that the real difference is the bug fixes that we
have made in LAM.
