That's interesting. May I suggest that you take a look at a book called 
"Temporal Data & the Relational Model" by C.J. Date, Hugh Darwin and 
Nikos Lorentzos 
(http://www.amazon.com/Temporal-Relational-Kaufmann-Management-Systems/dp/1558608559). 
It describes the best approach I've seen this far to dealing with 
temporal data.

Well, you don't need to run configure every time you want to build. If 
you just run "make", it will compile just the changes. I'd suggest 
running the configure with the --enable-depend option, so it picks up 
changes in header files better.

Also take a look at ccache (http://ccache.samba.org/). And if you have 
more PCs to spare, you might want to set up distcc.
