Hmm, the file compiles fine on my 64MB Linux machine with about 100MB 
of swap. What gcc version do you use ?

Anyway, once Christian is ready with his compact
replacement I think we no longer have to worry about that
chunk of static data :-)

Reading in the data from a file is not a very good solution,
because it would override the OS optimizations for static
data in object files (like e.g. swapping in only those pages
which are really needed, etc.).

An alternative solution would be breaking the large
table into several smaller ones and accessing it via
a redirection function.
