Initial Comment:

The following patch to the sisc script adds
-Dsisc.slib=$SCHEME_LIBRARY_PATH
to the $JAVA argument-list:

With SLIB-3a4, this modified sisc chokes because *features* changed to
slib:features between slib-3a3 and slib3a4:

  bash-3.1$ export SCHEME_LIBRARY_PATH=/usr/local/lib/slib/

When I tried to build from your source distribution (with
sisc/src/sisc/libs/slib.scm fixed) I get:

  bash-3.1$ sisc
  which: no rlwrap in (/home/jaffer/bin:/usr/kerberos/bin:/usr/java/jdk1.5.0_08/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/sbin:/usr/sbin:/usr/local/chipmunk/bin:/usr/java/jdk1.5.0_08/bin)

  ---------------------------
  Some stack trace entries may have been suppressed. To see all entries set the dynamic parameter suppressed-stack-trace-source-kinds to '().
  ===========================
  Caused by Error: library sisc/libs/srfi/srfi-59 not found

This is because the sisc-lib.jar built by running "ant" in the
top-level sisc/ directory contains no SRFIs, where the distribution
version does.  Where in the documentation does it explain how to build
the srfis into sisc?

So, instead I created sisc.init in slib/:
http://cvs.savannah.gnu.org/viewvc/slib/slib/sisc.init?view=markup

The "slib" script in the development version,
http://swiss.csail.mit.edu/ftpdir/users/jaffer/slib.zip now handles
SISC by invoking it "slib sisc".

I find that DEFMACROs in files which are loaded aren't visible in the
interactive top level.  I don't understand why.

I also have added SISC support to JACAL
http://swiss.csail.mit.edu/ftpdir/users/jaffer/jacal.zip invoked by
"jacal sisc".  Jacal-sisc runs all the mathematical tests, but chokes
trying to read /* */ comments!

  Error: attempt to apply non-procedure '#<character-input-port *prec:p...'.

I tracked down the error to a call at the end of
TOK:READ-THROUGH-COMMENT in slib/prec.scm.  The passed procedure STP
is a procedure (says PROCEDURE?); perhaps the problem is some call it
makes.
