Ship a Windows program written in Rust, and when it crashes or hangs on end-user’s PC you’re pretty much screwed. You need WinDBG to analyze these memory dumps written by the OS, and for that you need pdb symbols as opposed to dwarf.

C99 requires stdint.h, but does not require that fixed-width types exist; they're optional. In practice, every architecture you'd care to write C on (amd64, aarch64, ...) has fixed-width types.
