This requires us to record that the macros came from system headers and so did
the expansion.
Also -Wunreachable-code is useless for most cases in general because of
inlining and such.

Preprocessed test case
That's because I forgot to turn on -O2 :/

I don't see that htons was expanded as a macro there

Preprocessed test case
For what it's worth this is glibc 2.8 on Gentoo, AMD64 multilib system.

I cannot reproduce this because it seems that in my system
x86_64-unknown-linux-gnu, htons is not expanded as a macro.
Could you also add a preprocessed testcase and the exact output from the
compiler? Please, also use

tc-htons-unreachable.c
Sure here it is, there isn't much of a testcase I admit ;)

We need a complete testcase. See http://gcc.gnu.org/bugs.html
In this case, we would need the unpreprocessed testcase but we still need a
complete one that we can compile ourselves. Thanks.
