He didn't say it's missing, he says it's outdated.

IMO the detection (of the missing features) should be added to 
configure.ac and disable the code accordingly. We could also provide the 
header in the contribs and remove it when we require building with a 
recent enough version of Mingw64 (we need to determine which version has 
a usable version and document it).

We already have a recent mingw64 full tree in the contribs. That can 
probably be reworked so we can extract the header from there.
