I agree with your decision to leave boost::math::erfc alone.
I'm glad you were able to get rid of utils/ieee.h.
The one thing I would like you to fix (unfortunately in most of the files)
is to regroup the imports correctly (first standard headers, then 3rd party headers,
then finally LSST headers). Auto replacement is fine as a first step, but then
please look at each modified source file to make sure the grouping is still correct.
One question about the files in Jointcal: I see some of them still include boost/make_shared.hpp.
I thought you switched from boost to std for shared_ptr in an earlier ticket?
I'll leave it to Jim Bosch (the second reviewer) to mark this ticket as reviewed when he is ready.
