Presuming you have purchased a compiler that is beyond being someone's Science Fair Project, you aren't going to be turning up show-stopping bugs at every turn. By the time most projects are at some kind of "First Release" phase, in many cases you want to freeze the version of the compiler anyway (at least for embedded sorts of things this is rather common) so that from a configuration management and verification viewpoint you can work from a known quantity and be able to reproduce things properly. I'd definitely take new releases of a compiler for some time into a 30 year project, but well before the 30 years were up, I'd have frozen the compiler, the OS and the rest of the development platform - until some external reality forced me to move on! :-) MDC -- ====================================================================== Marin David Condic - Quadrus Corporation - http://www.quadruscorp.com/ Send Replies To: m c o n d i c @ q u a d r u s c o r p . c o m Visit my web site at: http://www.mcondic.com/ "Giving money and power to Government is like giving whiskey and car keys to teenage boys." -- P.
