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).
