Windows/WSL shouldn't change anything, gcc will have the same set of optimizations everywhere. There's just no inlining of the functions going on. There may be differences in the dispatching between different compilers & optimization levels, but none inline functions from a function list. It'd be a pretty messy optimization, as it'd need to check whether all functions can be inlined instead of just any single one (and increase the requirements if the call otherwise would be a tail-call, which cost a decent bit less), and it'd make it impossible to predictably do an actual function jump table if the compiler sometimes just didn't.
