The original gcc-4.3 release was in early 2008. If we decide to still support that, we probably want the first 10 quirks in this series, while gcc-4.6 (released in 2011) requires none of them.
It this min gcc thingy ARM only? The current minimium (documented) is gcc v3.2. With the -fno-PIE patches I was going to raise the bar to at least v3.4 but did not get around to it yet. hpa said that everything < 3.4 is broken on x86 [0]. Gert is getting code compiled on gcc v4.1 not sure if it is some kind of gcc limitation or just for fun. Unless people are stuck with some enterprise distro I don't see a reason why one should not try a gcc-4.6 which is 5 years old. I had problems to verify that the current kernel compiles with gcc v3.2 on x86 (it did with a bunch of warnings with gcc 3.4 and booted).
