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

Reported by: ngedmond Owned by: Jeremiah Willcock
Milestone: Boost 1.40.0 Component: integer
Version: Boost 1.39.0 Severity: Problem
Keywords: XMT MTA integer Cc:


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.
