Default integer types in boost/cstdint.hpp are incorrect on XMT/MTA

[ngedmond]

Integer types in boost/cstdint.hpp are not correct for Cray XMT/Tera MTA-2. The following patch works for me. I can't imagine any other compiler definines 'MTA' so this patch should be non-intrusive. Feel free to strip comments as appropriate.

Closing because this will be resubmitted as a new ticket.
