 I'm not sure about not that hard...
 
 Some testing shows the following:
 
 gcc 4.2.1 (on Mac OS) also has the issue
 gcc 4.5.0 (for MIPS/NetBSD) is ok
 gcc 4.6.0 (current trunk pre-release) is ok
 
 "ok" means it produces a warning "'noreturn' function does return".
 
 So one solution to this PR would be to update the toolchain to 4.5.1 =
 (the latest released gcc).
