Rather than this approach, why not have the glibc header include the

conditional on a sufficiently new version of the uapi header being
available, but it is more future-proof.


The kernel header cannot be used due to lack of name space sanity.

Exactly. Without feature selection macros such as _GNU_SOURCE, the setof macros which can be defined by <fcntl.h> is very limited.
