Right, because compilers can reorder some operations.  But we've been
living with this pre-C11 for decades.  We can't yet require C11 (though
I'd sure like to).

BTW, there's this:

which, IIUC means we can get C11 on Windows with MSVC with a clang
frontend.  So maybe Windows is a non-issue, and maybe C11 is a
non-issue.  Though I'm sure there's platforms where OpenSSL can't expect
C11 yet, so I suspect we're stuck with C90+ for a while.
