I fell like I start to understand where your hate for specifications comes from. As much as I like to stick to specs, which is generally OK for hardware and network protocols, I can say that with GCC, there is clearly no rule telling you whether your program will still compile with version N+1 or not. Can't we elect a recommended gcc version that distro makers could ship under the name kgcc as it has been the case for some time, and try to stick to that version for as long as possible ? The only real reason to upgrade it would be to support newer archs, while at the moment, we try to support compilers which are shipped as default *user-space* compilers.
