Sorry I can't help, but troll reply..
If you're intentionally combining everything into a single source for
optimization reasons - you can expect it to really stress and hit many
problems in the compiler.
If your code is just extremely poorly written or not organized well -
I'd encourage you to both file bug reports (of a more reduced nature
than 700ksloc) and refactor things so that it's better designed.
