Telemetry didn't compile under Windows.
Empty stubs implementation was added for Windows.

Maybe add a comment like /* RTE_EXEC_ENV_WINDOWS */ next to each #else/#endif, to be easier to follow what's being guarded out. Your guards are rather small,
so it's easy to follow, but sometimes when big chunks of code are being guarded, it's harder to tell what the guard was for (e.g. line 446 it's the end of a big #ifdef/#endif).
