gcc 3.3 doesn't compile the linux kernels (2.4 and 2.5) very well
currently because the inlining algorithm is too broken. The Linux
kernel often assumes that functions marked "inline" get inlined and
when they aren't it results in linking errors. In a few rare cases
you also get silent miscompilation (this happened in the x86-64 port,
now fixed)
Only good workaround currently is -Dinline="__attribute__((always_inline))",
just using -finline-limit=hugenumber doesn't help.
Better would be likely to fix the inlining heuristics to honor the inline
keyword better.
