Okay, I give up.
AFAIK, All C code must be inside a function, unless you count the
expressions in initializers.
So aside from certain CPU/MMU/OS/cache/etc. quirks, why would C code
inside a function run faster than C code outside a function? Compiler
optimizations because of const and restrict keywords don't count.
And what other C code *isn't* inside a function?
