Sorry, it's not there. It's silently ignored, which is the WORST POSSIBLE SOLUTION to the problem. Ugh.
The -Wunreachable-code has been removed, because it was unstable: it relied on the optimizer, and so different versions of gcc would warn about different code. The compiler still accepts and ignores the command line option so that existing Makefiles are not broken. In some future release the option will be removed entirely.
