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