This matches with Guy's analysis although it doesn't show that behaviour on my
system (which is too old no doubt). I will add code to detect that flag and if
it
works with gcc and older clang, then I will commit it and hope it will fix the
detection problem on systems with newer clang.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
