This is an attempt at using dlmalloc v2.8.4. Its a work in progress, but wanted to post to see what peoples feelings are on updating. This version resolves all the various warnings we see w/gcc4.4 and the older version of dlmalloc however the trade of is the code size has increased.
I still need to see if we need to hand relocate the global structs or not.
This diff is just of malloc.h to see how things are cfg, and of dmalloc.src vs dmalloc.c to see the changes to it.
