Bug#811449: bagel: FTBFS: size_t is assumed to be the same size as long long

[Aaron M. Ucko]

Source: bagel
Version: 0.0~git20150902-1
Severity: serious
Justification: fails to build from source

Builds of bagel for 32-bit architectures such as i386 have been failing:

  mpi_interface.cc: In member function 'int 
bagel::MPI_Interface::iallreduce(size_t*, size_t)':
  mpi_interface.cc:181:3: error: static assertion failed: size_t is assumed to 
be the same size as long long
     static_assert(sizeof(size_t) == sizeof(long long), "size_t is assumed to 
be the same size as long long");
  ...

Could you please take a look?

Thanks!
