setjmp is a macro expanding to _setjmp or _setjmpex. In soviet russia and on ARM builds, the compiler will convert invocation of _setjmp back into a call to setjmp. The compiler handles _setjmp and _setjmpex in the same way, generating code where r0 points to the jump_buf and r1 points to the current functions stack frame (sp on function entry). So make setjmp and _setjmp aliases to _setjmpex and make the latter use r1. svn path=/trunk/; revision=67729
