In my opinion, not really! Can't that be solved by a more generic define
or something like that?
I'd imagine other comilers have that problem, too, which would end in
'#if A | B | C'...

I'm afraid I don't really understand the problem, I think, so correct me
if I'm wrong:

gcc4 gives an error 'return value not used' in pbuf.c:pbuf_realloc()
with MEM_LIBC_MALLOC=0?

Other solutions would be:
- removing the return value from mem_mrelloc()
- or really using the return value in pbuf.c so CLIB realloc() can be
used (even if we don't use it with our mem_realloc())
- '#define mem_realloc(x, size) (x) = realloc((x), (size))'  so that x
is updated

Instead of 'wasting' memory on suchs targets...
