lowering OSPF memory requirements

First of all, configure out all protocols you don't use.

Another thing which could help is switching off BIRD's smart allocators to the
system ones which are slower, but more memory efficient. You can try changing
"#undef FAKE_SLAB" in lib/slab.c to "#define FAKE_SLAB".

(Untested, but could help a lot.) Try linking bird with diet libc (see
http://www.fefe.de/dietlibc/) or uclibc (http://www.uclibc.org/).

In any case, I'll be very glad to hear about the result.

				Have a nice fortnight
