[Bf-taskforce25] RNA compile troubles

[Nathan Letwory]

Hi all,

Our new RNA system is great for automation, but also, the way it is
currently implemented it generates a HUGE rna.c, as of this writing I
look at a 47031 line C file in 1645KB. While this is nice on machines
with loads of RAM, it is already a problem on low-end machines.
Compiling on linux with 777MB or less will just fail. For one, there
will first be a huge amount of swapping (esp with 0.5GB), and at some
point the GCC compiler will die because of an internal error. On the
box I tested with I have a swap of 700MB.

There have been reports by others with similar low-end (or even
lower-end) system that compiling rna.c will just fail at some point.

I think it would be good to think of ways to have rna.c chopped up
into bits so that the compiling still can be managed successfully.
