It's not easy, unfortunately.  You might get some insight into the
reasons why isn't this easy if you read Chapter 15 of the DJGPP FAQ
list.

One possibility to estimate the maximum memory usage is to call
sbrk(0) near the beginning of the `main' function and right before
you exit; the difference between the two numbers will give an
approximation of memory allocated dynamically.

If that is not good enough, perhaps you could tell more about why do
you need to know the maximum memory usage.
