I just tried upgrading from g++ 3.3.1 (which currently gives me an

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
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.
ICE is probably the fault of the compiler, regardless of any possible
shortcomings of your source code. Other than that, I have no disagreement
with Mikael. If you "fix the code" and still provoke problems, there is
some advantage in submitting bug reports against a version which is
currently actively maintained.
