// mfh 30 Jan 2013: Thanks to Jim Willenbring for reporting this, and
// to Mike Glass and Paul Lin for updating the fix for dealing with a
// bug in IBM's XL C++ compiler.  The update was necessary due to a
// relapse of the bug in a newer version of the compiler.
//
// If you don't have this update, you can fix the problem by defining
// the macro TEUCHOS_TYPE_NAME_TRAITS_OLD_IBM when compiling anything
// that includes this header file.  If you have the current version of
// this file, then you don't need to do anything.
