What will this C code do?

void main(){
int x=1;
printf("%d\n",x=2);
}

Just look at GNOME or the Linux kernel.

I smell bullshit. The reason why GNOME is crap is because the homos on that project decided to do an entire code rewrite instead of fixing the existing bugs. This is because, as you probably don't know, it's just far easier to rewrite the crap and "get it right this time".
