Thanks for the feedback and no worries, I'm no saint in that regard either.

Before I post a v2, did I understand the following issues correctly?

_BSD_SOURCE currently exposes the AT_STATX_* flags in fcntl.h.

2. uint64_t -> unsigned long long guarded by #ifdef __GNUC__
__extension__? Or just leave it as-is?

4. An ENOSYS fallback to fstatat()? glibc's fallback returns EINVAL
for AT_* flags it doesn't understand and ignores all STATX_* flags: it
sets stx_mask to STATX_BASIC_STATS, fills in stx_uid/stx_gid/etc. and
sets stx_btime to zero. Does that sound reasonable?
