If Kaffe itself doesn't use the libc.a version of malloc/free, you can
write yourself an "interlude":
void * malloc( size_t a )
Then the same for free().
Link this object with your program before searching the libraries and
all references within your objects and those of the libraries you link
with should find your version of malloc/free. No recompilation
necessary. Note that any code you can recompile, you should recompile to
avoid the overhead of the interludes.
One possible twist is that these other libraries may rely on other
incompatible memory allocation systems which interfere with gc_...
routines' use of the heap. But, one step at a time!
Hope this helps.
