You could just use the benchmarks game measurement scripts - 

http://shootout.alioth.debian.org/u32q/faq.php#measurementscripts

They already report the time to complete all the MAKE actions - it wouldn't be difficult to break that out to show compile time.

They already sample memory use, and record cpu time, elapsed time, source size - it wouldn't be difficult to get the executable size.

But if you're having fun writing a measurement program... ;-)
