bug in configure.in

[Herb Lewis]

The following lines exist in configure.in and contain a bug. I'm not
sure of the original intent so I hesitate to change it. If you have
a value set for CFLAGS, this code in effect duplicates the contents. 
Who made this change and what was the intention?

# compile with optimization and without debugging by default
OPTIM=${CFLAGS-"-O"}

AC_ARG_ENABLE(debug, [  --enable-debug        turn on debugging
[default=no]],
    [if eval "test x$enable_debug = xyes"; then
        OPTIM="-g"
    fi])

CFLAGS="${CFLAGS:=} $OPTIM"
