I misread the gdb documentation.  In the doit() function of the 
/usr/bin/mlton.debug script, you should change:
    exec "$mlton" @MLton ...
to
    exec gdb --args "$mlton" @MLton ...

That starts up mlton-compile.debug under gdb for me.  Of course, it may 
not help if gdb doesn't recognize the executable in the first place.
