Granted.

True enough.

Yup.

Give me flexibility.

Because I don't want to force a static data segment.  Under Unix,
malloc calls sbrk() which calls brk().  Under Amigix, malloc() will
call AllocMem() and sbrk() and brk() will be be either sumplistic or
dummy-implemented.

As for the ANSI memory functions... well, the BSD ones aren't _that_
nonstandard.  But no reason not to have both ANSI and BSD ones.  For
example, bcopy() and memcpy() can be the same routine, just two
different ways to call it.  (2 stub routines & 2 #pragmas)  I know the
arguments are in a different order.  The stub routines and pragmas can
handle loading the registers in a different order without having to
change the actual routine.

One problem I have is that I don't have any really good reference for
ANSI library functions...

As for library calls vs. system calls, the division may not be the
traditional ones.
