that's what I experienced in similar situations: the compiler works and works, 
allocating a lot of memory, and the system struggles with swap for a long time 
to make it work (possibly because the compiler keeps allocating memory) until 
all swap is exhausted, and only then it bails out.

by allocating a lot more swap you can keep that from happening, but it will 
still be very very very slow.

compiling without -O2 reduces the memory usage (apparently drastically), so 
that everything still fits into RAM, which is simply blazingly fast compared to 
the disk.

except that it hasn't got much RAM? probably not.
