  5. * This test ensures (at compile time) that some types have the expected size in
  6. * C. The purpose is to ensure that the ABI of PPAPI is known, consistent, and
  7. * stable. Only structs that have architecture-dependent size are checked by
  8. * this test. These structs use at least one type which differs in size between
  9. * 64-bit and 32-bit (e.g. pointers or long). By convention, we require other
  10. * types to be of consistent size on 32-bit and 64-bit architectures.
