OK, I see the problem now.  Some programs insist on demanding the
optimizing options you use, which is crazy, so I always strip them out:

  # Stop the MySQL config program adding -O<n> options to CFLAGS
  mysql_cflags=`$MYSQL_CONFIG --cflags | sed -e "s/'//g" -e "s/-O[1-9]*//" `

I also do this later on, but *ONLY when redland is built in maintainer mode*:
  CFLAGS=`echo $CFLAGS | sed s/-O[1-9]*//`

So I need to make the regexes more powerful.  In this case, using
  -e "s/-O[A-Za-z0-9]*//"
in the sed lines.

If somebody wants to add optimizing, there are two places you
want to do it:

1) When compiling redland itself
  CFLAGS="-O255" ./configure ...
  make

2) When building with redland

  gcc -o foo foo.c -O255 `redland-config --cflags` `redland-config --libs`

  rather than have redland-config --cflags override everything.

  (or equivalent with pkg-config redland --cflags)
