#3177: Default integer types in boost/cstdint.hpp are incorrect on XMT/MTA
-----------------------------+----------------------------------------------
 Reporter:  ngedmond         |       Owner:  dlwalker
     Type:  Patches          |      Status:  new     
Milestone:  Boost 1.40.0     |   Component:  integer 
  Version:  Boost 1.39.0     |    Severity:  Problem 
 Keywords:  XMT MTA integer  |  
-----------------------------+----------------------------------------------
 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.
