g++ version 3.4.x is alot less forgiving (read: more compliant) than
earlier versions of g++ (GCC) were regarding standard C++. This is a good
thing.
I haven't used the test version you mention but I've been compiling my
own versions of GCC under Cygwin for some time and right now
I am using the latest version (3.4.3). I haven't had any problems other
than not being able to use -mno-cygwin anymore but I can live with that.
So, you probably have problems with your C++ code, i.e. it's not standard-
compliant but GCC used to accept it. Crank up the warning levels and turn
off compiler extensions and start fixing the code.
