On a big endian system, comparing integers with memcmp works correctly because higher-rank bytes are compared before lower-rank bytes. On a little endian system, lower-rank bytes are compared first, which would make e.g. 256 less than 1. Porting code that relies on comparing arrays of structs for ordering is likely to be a nightmare. We really need to fix this. -- Andrei
