Just to be clear, compiled PreScheme programs do use malloc() and free().
If you look at prescheme/test/write.scm, 'allocate-memory' and
'deallocate-memory' compile to calls to malloc() and free().  As Mike says,
it should work fine with Boehm's GC as long as your program doesn't itself
do anything odd with pointers.
