I need to override memory allocation functions in SCO port of my app
(now running on Linux and SCO. I could not dump SCO support just yet).
So how could I backport calls like:
c_free = (void (*)(void*))dlsym(RTLD_NEXT, "free");
given that RTLD_NEXT seem to be something specific to Linux (other UNIXes
including SCO seem to be lacking that macro).
