Some inconsistencies concerning OpenSSL include configuration in FRS 3

However, maybe the failure is better than a wrong header file...

  The issue is that the CPPFLAGS are *supposed* to be passed from the
main configure script to the lower-level ones.

  Hmm... what happens if you edit the top-level "configure" script?

- go to the bottom, and then look backwards for "werror"

- you should see:

if test "x$werror" == "xyes"; then
  CFLAGS="-Werror $CFLAGS"
fi

- after that block, add:

export CPPFLAGS CFLAGS LDFLAGS

- then re-run configure

  That should hopefully fix it.  If so, I'll commit a patch.
