I was wondering about this whole business, and the manifest approach
is a *horrible* design for an API where the goal is to know if your
run-time environment is greater than a given threshold.

Hmm.  That depends on the dependency set, I guess.  We do that on
Linux at some extent to for large pages in sysv_shmem.c.  Perhaps this
could work for Win10 if this avoids the extra loopholes with the
manifests.

Are we sure that this is not going to cause failures in environments
where the flag is not supported?
