Looks like I misread in configure.ac, TearFree is not enabled by default.

[ configure.ac ]

AC_ARG_ENABLE(tear-free,
     AS_HELP_STRING([--enable-tear-free],
    [Enable use of TearFree by default [default=no]]),
     [TEARFREE="$enableval"],
     [TEARFREE="no"])
if test "x$TEARFREE" = "xyes"; then
AC_DEFINE(TEARFREE,1,[Enable "TearFree" by default])
xp_msg="$xp_msg TearFree"
fi

So forget this braino.
