Can somebody
let me know if the following code can be compiled by a more recent
version of gcc or some other compiler?
The gcc folks themselves use the EDG front end to check bug reports
against gcc/g++. The EDG front end is used by Intel's ICC compiler and
many others. There is a great online service through which you can try
your code against this compiler:
http://www.comeaucomputing.com/tryitout/
I heavily use this Comeau service, not only for actual gcc bugs (I've
reported a ton) but also to make progress when the bug is between my
ears and gcc is not being helpful. The EDG diagnostic quality is way
beyond gcc - they even do a better job of the cryptic error message
stacks from template metaprogramming.
