// Define ROSE_PARTITIONER_MOVE if boost::move works. Mainly this is to work around a GCC bug that reports this error:
//
//   prototype for

//   does not match any in class 'Rose::BinaryAnalysis::Partitioner2::Partitioner'

// followed by saying that the exact same signature is one of the candidates:
//
//   candidates are:
//   Rose::BinaryAnalysis::Partitioner2::Partitioner::Partitioner(boost::rv<Rose::BinaryAnalysis::Partitioner2::Partitioner>&)
//
// This is apparently GCC issue 49377 [https://gcc.gnu.org/bugzilla/show_bug.cgi?id=49377] fixed in GCC-6.1.0.
