It is a bit difficult to extract useful information from these
resources.

Is off_t 32 bits?  Why is the ia32 compatiblity kernel interface used?
I'm sure a lot of people want to get rid of that in cases where they
control the whole software stack.

Is stack alignment to 16 bytes beneficial for X32?
