compile error on Mac OS X 10.3 (Panther) and the patch

[js]

Hi,

Compiling memcached(svn trunk ver) failed with these errors.

$ make
make  all-recursive

This is because OS X 10.3, unlike 10.4, doesn't have IOV_MAX in limits.h.
Below is my patch.

__APPLE__is the flag for darwin.

I don't know whether this is right fix or not
so could someone please review this patch and accept this or write better patch?

Thank you in advance.
