The bottom is not very deep, afaics. I've basically seen two things:

* The absence of an `asm` statement with c99. Because it's not a reserved keyword, the compiler has to allow it as an identifier and can't define it itself.
* On some hosts some combinations of feature test macros don't work. We could blame libc developers for that. We could try to patch bad libc implementations and upstream everything. But if we want it to compile for the random person who seeks help on IRC, I don't see how we can do better than adapting to odd environments.
