Just in case, let me throw in a side note: you almost certainly don't 
have to go as far as compiling "on" a 32-bit system to achieve that.  It 
will be quite sufficient to compile _for_ a 32-bit system.  I.e. all you 
need is a cross-compiler for a 32-bit target platform (e.g. Win32 
instead of Win64).

I don't really think that's true for C++ as a language.  It may well be 
a true statement about people programming in C++, though.

There was a time when compiler technology didn't manage to keep up with 
the demands of the C++ language specification.  Template instantiation 
created a whole lot of new and interesting problems, which took quite a 
while to sort out.  Linkers in particular have to be a whole lot better 
than they used to, otherwise the sizes of C++ programs liberally 
utilizing templates would have exploded beyond all reason.
