Comment 2 connor-gh 2023-11-23 06:46:55 UTC

This is harmless in regards to security, but it'd be nice to fix.

The functions that are implicitly declared are:

unreachable() -- tested for in the configure only (perhaps it falls back to __builtin_unreachable() ?)

MIN -- macro tested for in the configure only

_snprintf -- obviously not used and probably just here for OS X weirdness

alignof -- only supported in c2x and clang does not default to that for obvious reasons. _Alignof works though

static_assert -- same reason as above, _Static_Assert works
