Are you sure you understand the problem I was trying to solve? I am
using dlmalloc's existing means of adding a prefix, but I'm sure we
could change it to another way.

If we define malloc() as dlmalloc() in dlmalloc.c, then we could add a
declaration in dlmalloc.h that uses static inline to convert calls to
malloc() to call dlmalloc(). Then anything that doesn't include
malloc.h would still call the C library malloc(). Is that what you are

I did look at using a link script instead but it is pretty messy.

What do you mean by 'free' being a reserved keyword? Where? So is
'rfree' a good substitute or do you suggest something else?
