problem making swarm-1.4.1 (-O3) under rh6.0

[Rick Riolo]

I have just had a little surprise.
I first made swarm-1.4.1 using the default ("debug") settings:

cd /usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/builds/debug
export SWARMSRCDIR="/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1"
export CC="/usr/bin/egcs"  
$SWARMSRCDIR/configure \
   --srcdir=$SWARMSRCDIR  \
   --prefix=$SWARMSRCDIR/debug \
   --with-ffidir=/usr/local
make
make install

and it made just fine, and a heatbugs made off it runs just fine.
(there were some warnings at link time, but that's a different 
story I think, so I'll skip it for now...)


However, I then tried to make an "opt" version:

  cd /usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/builds/opt
  export SWARMSRCDIR="/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1"
  export CC="/usr/bin/egcs"  
  CFLAGS=-O3 $SWARMSRCDIR/configure \
  --srcdir=$SWARMSRCDIR --prefix=$SWARMSRCDIR/opt --with-ffidir=/usr/local
  make

but this make stopped unexpectedly!  Here is the place it stopped
(there is probably some strange line wraps below):

...

I thought I'd try to see why it stopped:

address@hidden opt]$ cd 
/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/builds/opt/src/objectbase
address@hidden objectbase]$ /usr/bin/egcs -DHAVE_CONFIG_H -I.

/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/src/objectbase/swarm_rts_routines.m:
In function `skip_typespec':
/usr/local/swarm/Swarm-1.4.1/swarm-1.4.1/src/objectbase/swarm_rts_routines.m:30:
warning: `type' might be used uninitialized in this function

Line 30 is the last line here:

  const char* 
  skip_typespec (const char *type)
  {
    type = skip_type_qualifiers (type);
 

So...any ideas as to what the problem is here?
What is puzzling to me right now is why the "debug" (ie no -O3) worked
fine, but this opt version is failing here.
(Note that I actually  went back and compiled that same swarm_rts_routines.m
file in the debug tree, using the compile command above but with no -O3,
and there was no warning!)
  
thanks.
