Just because removing a platform include file works in some environment is
*NOT* sufficient to remove platform include files. There are a lot of
variations between platforms about when some include files are implicitly
included via other include files. Just removing them because it works on one
platform ends up with more niche operating systems failing to build, which we
may only figure out months or even years down the road.

At the very least you need to figure out why the includes where added and why
that reason is not present anymore.
