I've moved this to http://people.freebsd.org/~imp/smaller-mips.diff for =
nicer downloading, and the original link had too many l's in it...

Btw, the extra initialization is for a few places where -Os produces =
different (and I think spurious) warnings vs -O2. That's also the =
purpose of the MIPS_SMALL_HACK option, so the three shift routines that =
are normally inlined by the compiler have definitions. But those few =
bytes may not be worth optimizing...
