Could you specify which Smalltalk you are going to use. Using Digitalk V286,
it is not a very hard problem. You can use almost any C compiler and some 
assembly glue to connect Smalltalk and your C subsystem. For Smalltalk 80, it
is a bit harder. You need the phar lap dos extender tools and a Watcom
or NDP compiler, I think. For Smalltalk V on the mac it is very easy, you just
make an XCMD. If you specify you environment, I could give you some more
pointers.
