-R, --requires
List packages on which this package depends.
$ rpm -qR glibc-devel|grep ^glib
glibc = 2.9-2
glibc-headers = 2.9-2
As -R/--requires lists any sort of Requires() [even post/postun/...],
the results of this query are misleading, at least. A requirement
that is not a requirement, because rpm -e ignores it.

That ought to be fixed in glibc-devel, then.
glibc-devel doesn't do anything in %pre that would require glibc-headers.
Perhaps it used to be PreReq (I won't look at old pkg releases now).
Changing the Requires(pre) into a normal Requires would be plausible.
The packages share a single %_includedir/gnu -- erasure ordering is a
mess anyway with regard to unowned directories and complex dep-chains.
It would not be wrong to include the directory in both packages.
