AFAICT current sources don't actually use "-l" anywhere.

However, it does appear that we can tweak flex for more performance
(usually at the expense of a larger generated parser). In particular, it
looks like we could use "-Cf" or "-CF". Is this a good idea?

While we're on the subject of minor optimizations, is there a reason why
we execute gcc with "-O2" rather than "-O3" during compilation?

Cheers,

Neil
