Error Running jextract on d3d12.h

Hi Michael,

Thanks for trying out jextract!

Not at all :)

It looks like you are using the pre-built binary from jdk.java.net? Note 
that that one is pretty old. We are planning to update it in the near 
future, but if you don't want to wait, you can also try building the 
panama JDK yourself. The repo is found at: 
https://github.com/openjdk/panama-foreign See doc/building.md [1] for 
instructions (though you'll have to substitute mercurial for git, as the 
doc has not yet been updated after the recent mainline transition [2])

In the time between that binary coming out and now, there has been a 
complete re-write of jextract. With the current version I gave 
extracting d3d12.h a try, using the following commands (powershell):

     $jdk = <path to built jdk>
     nal -Name jextract -Value "$jdk\bin\jextract.exe"
     $I = "C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0"
     jextract -d out -t org.jextract -I "$I\um" --filter "d3d12.h" -- 
"$I\um\d3d12.h"

But I ran into a problem for which I've filed: 
https://bugs.openjdk.java.net/browse/JDK-8252899

I'll try and see if I can get the extraction of d3d12.h working.

Thanks,
Jorn
