This patch is incomplete and introduces a few other problems (at least warnings about unused functions), but it shows what we would have to do in order to address this in the kernel. The three options forward I see are: - Declare gcc-4.5 (and prior version) fully supported and do proper fixes for the bugs we find. - Officially declare gcc-4.6 the minimum required version for the kernel and remove all existing hacks we have for older versions. - Do nothing: if you use an older gcc version and you run into this, you are on your own and can submit a patch for the specific problem you find. At the moment, gcc-3.2 is in theory still supported, but I found that even gcc-4.2 is almost completely useless these days at least on ARM. If we want to keep gcc-4.5 supported, then we can probably have 4.3 as the minimum version without too many other workarounds. Do not apply but feel free to pick out parts of this patch and submit them if you use old gcc versions and run into the problems.
