Change 138006 by rrs at rrs-mips2-jnpr on 2008/03/18 13:58:07

	This adds back the cprestores (to keep the compiler happy
	       even though we don't do any jumps) and instead sub a callframe
	       from the stack (and add on _setjmp, not needed on _longjmp
	       since we restore the old stack)
