Remember the #arg and ##arg mess in macros between gcc2 and gcc3 ?
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.
