That is true. Contributions are more than welcome. > Is off_t 32 bits? Why is the ia32 compatiblity kernel interface used?

The current thought is the x32 user space API is the same as is ia32. time_t is also an issue. > Is stack alignment to 16 bytes beneficial for X32? > Even ia32 uses 16byte stack alignment and we will make it official soon via an amendment to the i386 psABI. -- H.J.
