I just tried upgrading from g++ 3.3.1 (which currently gives me an "internal compiler error" on my code) to the 3.4.1 version available from the Cygwin setup. After doing so, however, I get a flood of error messages about the many templates I have (such as "template-id xxx for yyy does not match any template declaration" and several other).
Should I start to adapt my code to gcc 3.4.1, or would it be safer to wait until it is available as default from the setup? Is it likely that the error messages I get is due to the Cygwin port, or would it be g++ itself?

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.
