Nice!  I have to read about this more.  In any case in separate
files in not worse!  I think this malloc make other improvements also ;-)

I copy/paste PAGE_SIZE from dietlibc alloc.c
It is not so important in my code.  I have looked on
Enrico site and seem that ELF aux vector is a good idea.
I can make easy changes to avoid using PAGE_SIZE macro.
I need this macro only for mmap(2).  If Felix accept my alloc
and new get_page_size_method is default in dietlibc,
then I'll update my malloc.

Thanks for the interesting info Enrico!
