Not certain I asked the question right.  Or perhaps I'm just invoking
wrong.   In the following gcj command, no matter where I put
   -L$TLIB -ljsapi
I still get missing classes errors.  But if I instead include
   -I~/tts/freetts/lib/jsapi.jar
which that libjsapi.so file was compiled from in the -I list, everything
is okay.  My assumption is I should be able to not use -I and
instead pick up the -ljsapi somehow to inform gcj re how the
missing classes would look.

   gcj $GCJ_FLAGS \
       -I /opt/IBMJava2-142/jre/lib/graphics.jar  \
       -I ~/tts/freetts/lib/cmulex.jar \
       -I ~/tts/freetts/lib/en_us.jar \
       -c -o $TLIB/libfreetts.so \
       $CVS_DIR/tools/lib/freetts.jar \
       $CVS_DIR/tools/lib/cmulex.jar \
       $CVS_DIR/tools/lib/cmu_us_kal.jar \
       -L$TLIB -ljsapi \
      
$TLIB/libjsapi.so exists.   It was created by:
   gcj $GCJ_FLAGS \
       -c -o $TLIB/libjsapi.so \
       ~/tts/freetts/lib/jsapi.jar

I'm guessing this is such a simple thing that it's painfully
obvious to everyone else on the list.  I apologize for this
basic question.
