valloc allocates memory aligned to the page size. It's currently implemented
by calling memalign.

I don't know about memalloc.

mmap allows files or devices to be mapped into memory. You can also use mmap
to allocate memory. DJGPP does not support mmap.

So as far as I can tell, the only function that needs reimplementing for
nmalloc to go in is memalign. So hopefully it's not as bad as it seemed.

Bye, Rich =]
