[Dune] Comment on compiler discussion.

[Robert Kloefkorn]

Dear folks,

just on comment to the question whether to drop gcc 3.4.x and icc7.

To my opinion we should drop the support of these old compilers.
Nobody is using these anymore. Otherwise, some people would complained 
about code that is not compiling much earlier. Also, to maintain the 
software for various compiler is more time consuming, time that we could 
use to do better things (e.g. make SGrid faster....).

Standard conformity of a compiler does not mean much. There is a C++ 
standard, ok. But actually the standard is defined by the compilers 
mostly used, whether you like it or not. And this is why we have to 
stick to what the compilers we want to use (all of them) allow us to do.

 From this point of view we should support standard compilers compilers 
such as gcc4.1.2 and gcc4.3.4, for example. Also, the current version of 
icc (or that not to old version somebody has a license for). It might be 
clever to also support compilers like xlc, if possible.

Best Regards,

R
