Either you misunderstood what I was asking or I wasn't quite clear in what I
wanted. ;)

I want to know if I can modify OPTS in CONFIGURE and have the $OPTS used in
BUILD have those changes. I just tested with today's (20040823) Sorcery and
OPTS is not saved between files (at least from CONFIGURE to BUILD).

What I wanted (and should be able to do so we can continue to use 
default_build
in spells that need extra configure flags) is in CONFIGURE I ask if they want
Midi support (snd spell):

config_query  MIDI    "include sndlib midi module?"  n
...
if  [  "$MIDI"  ==  "y"  ]
then
  OPTS="$OPTS --with-midi"
fi  &&
...

And have those options added to OPTS in BUILD, yet when I do `echo OPTS = 
$OPTS`
in BUILD I get this:
OPTS = --with-gl --with-ladspa --with-gsl --with-fftw

So how do we go about modifying OPTS? Or do we have to add BUILD files and 
make
more variables, such as:
CONFIGURE:
config_query  MIDI    "include sndlib midi module?"  n
...
persistent_add  MIDI_OPTS  &&
if  [  "$MIDI"  ==  "y"  ]
then
  MIDI_OPTS="--with-midi"
fi  &&
...

BUILD:
./configure  --prefix=$INSTALL_ROOT/usr  \
             --with-static-xm            \
             $MIDI                       \
             $OPTS                       &&
...

snd is slightly a bad example as it already has a BUILD file so my main caveat
with this method (needing BUILD files just to add options) isn't that great,
but it's what I'm working with right now. ;)
