Re: building with debugging turned on

Each version comes with a copy of the installation instructions.  For  
example,

	http://smlnj.org/dist/working/110.58/INSTALL

If you install using the config/install.sh command, then you should  
be set.  The
makefile already uses the -g option to compile the runtime, so you'll  
just need
to run gdb on it.  For example, if you are in the src/runtime/objs  
directory (where
the runtime is built), do the following

	gdb ../../../bin/.run/run.ppc-darwin

and then

	run @SMLload=../../../bin/.heap/sml

at this point, you'll have SML/NJ running under gdb.
