I see the "limit it to 500 lines", but I don't see any real coherency.

So I take it that if you upgrade your gcc version, you may need to
blow this cache away manually?

Or is there something subtle going on that I've missed?

FWIW, I still think we should probably make the compiler versions etc
available to the configuration management rather than necessarily
cache them.
