// Some ports make the mistake of running a 32-bit userspace
// on a 64-bit kernel. Shame on them. It's not at all OK to
// make everything "long long", since that causes unneeded
// slowness on 32-bit hardware.
//
// SPARC: The 32-bit kernel was looking like an ex-penguin,
// but it lives! ("I'm not dead yet.") So, 64-bit users will
// just have to compile for 64-bit. Aw, the suffering.
//
// MIPS: Used 32-bit for embedded systems and obsolete hardware.
// The 64-bit systems use an n32 format executable, defining
// _ABIN32 to indicate this. Since n32 doesn't currently run on
// any 32-bit system, nobody get hurt if it's bloated. Not that
// this is sane of course, but it won't hurt the 32-bit users.
// __mips_eabi means eabi, which comes in both sizes, but isn't used.
//
// PowerPC: Big ugly problem! 32-bit Macs are still popular. :-/
//
// x86-64: So far, nobody has been dumb enough to go 32-bit.
//
// Unknown: PA-RISC and zSeries
