and this is the case because of C, which was my point. The fact that OS'es are written in C and thus have a C libraries and APIs is why you must respect C's rules for identifier names.

Also, yes compilers for other languages essentially name-mangle anyway, that's how (modern) fortran which is case sensitive and C++ which isn't (but tacks on a bunch of things to function identifiers) work. But the point about naming conventions or recommendations still stands, like a lot of things it is a fact of history favoring C, not that there is anything inherently better about it.

I believe it was already the case prior to C with assembly, and really because originally only one case (uppercase) was available. C just didn't change anything about the case-sensitivity of linking.
