OK. So, what else?
As steven asked, I'd like to understand why this is not a problem
for the C++ community.  There are several alternatives

1) The C++ programs are smaller than the java programs
2) the c++ representation is denser
3) the c++ users have more memory
4) The ones the C++ community *has* complained about are seen as
pathelogical cases or acknowledged IR deficiencies
5) The c++ community are too timid to complain

I haven't seen it.

It was basically 'get more memory'. I'd like to understand if you're really talking about 'when I compile this humungous source, I need a lot of memory', or if it's 'when I compile this source, I use more memory than is reasonable'.
