NSS, cURL, Boost, and multiple Perl pods all define their own `quick_exit` methods or variables. Debian Code Search may find more; this is just what I have local in /usr/src.
It is also a hard-fail from PCTS (the POSIX Conformance Test Suite) for an implementation to have visible definitions in the main namespace that are not defined by the standard.
It also ensures that -std is specified properly by upstream packages. We have already reported multiple instances to upstreams of their not specifying the correct standard version in their build recipes, causing spurious failures. I can find some of these reports if you need them.
Best,
