I get it (having reread that section, and the equivalent bit of the GCC
documentation, several times).  This is because it would somehow merge
duplicate definitions, yes?  So if you said "int x; int x;" it would
merge tham and then generate code to destroy 'x' twice?  Sounds like
a bug in GCC to me, not a (mis)feature; does any other C++ compiler
have this problem?

In the meantime, it sounds as though compressing the executable is the 
answer.  Or are there problems with that as well?
