We'll need to see actual code snippets that misbehave before we can help.
However, judging by your example below, I can guess that most of these are
against the general C++ coding practices. GCC 3.4 is much stricter in
that regard than previous versions, and does not necessarily try to make
sense of such code, which is probably what's happening in your case. Did
you try compiling with "-Wall"?

"i=i++" is either a no-op or nonsense, depending on the interpretation.
You should either use "i=i+1" or "i++" (those should be equivalent in
modern compilers).

That's for you to say, but I suspect your code would benefit from some
review and rewrite. Google for "C++ code style guide".
