I have put Peter Gibbs' changes into generic.c, and implemented alloc, free and (hopefully) realloc in win32.c. Updated other platform files to have these functions (and just call into the normal mem_sys ones) and updated platform_interface.h. I'm not too sure what is required in terms of changes in jit.c, so I followed Peter's lead there and also added a #include at the top. It's attached as a separate patch. Hope this helps, Jonathan [1] What are the semantics of mem_flush_executable? I didn't implement this.
