cygwin rename instead of link (7.2.2)

The fix will appear in 7.3:

#if !defined(__BEOS__) && !defined(N_PLAT_NLM) && !defined(__CYGWIN__)
if (link(tmppath, path) < 0)
elog(PANIC, "link from %s to %s (initialization of log file %u, segment %u) failed: %m",
tmppath, path, log, seg);
unlink(tmppath);

We could have back-patched this into 7.2.2, but one thought of it. Sorry.

Here is a patch against 7.2.2 to resolve it:
