Well, for Apache 1.3, you definitely can't use the APR UUID stuff :-)
On Windows, for 1.3, you can simply call CoCreateGuid() and be done with it.
And the Windows guids are unique.
[ I seem to recall this thread started as a result of a Windows problem;
UUIDs would solve it for that platform. maybe it was Netware? ]
Regarding APR's UUID solution: if you think it isn't "good enough", then I'd
be interested in knowing. It collects a decent amount of see and then hashes
it to get a "random" result. If there is more seed data that we could use,
then we should.
