The point I was trying to make (although perhaps not clearly enough) is 
that there is no reason that a trivial source file takes up such a huge 
amount of memory to compile. Especially since gcc 3.4.6 does not blow up 
like that.

If every new gcc version means I have to readjust the amount of memory in 
my box, I guess I'll pass the next time a gcc upgrade happens. This is not 
what I would call progress.

Anyway, I will get back under my stone now. :)
