Of course! That's why my message said 4 gigabytes of sources and not
four gigalines.

But Four thousand million characrters of sourcers is a heck of a lot.
This is typically a hundred million lines of source. I doubt there are
any programs in existence where a single compilation requires a hundred
million lines of source!
