Since when does developer ignorance require workarounds in the compiler? If I
"don't really think" about how I write my iterator loops, I fully deserve to
have buffer overflows (although, if the compiler can be smart enough to
generate a warning, that would be great!). Likewise, if I declare all my
functions inline, then I deserve to get an incredibly bloated compiled
executable. That's the spirit of C - do what I say, not what you think is good
for me. If I wanted the latter, I'd be using Java.

Looking at that gave me the shivers :) Whoever wrote that code definitely
didn't think about what should be inlined and what shouldn't be. They have
inline functions a hundred lines long! I would say they got exactly what they
deserved - slow compilation and a lot of bloat. If you write bad code, the bad
code should be fixed, not the compiler, which is even in this case doing just
what it is told to do.
