Periodic jextract failure on Windows

[Jorn Vernee]

Hi Duncan,

You are likely running into: 
https://bugs.openjdk.java.net/browse/JDK-8240614

I've looked into this previously and it seems to be an issue deep within 
libclang itself.

It's an older issue, but since the workaround is so easy (re-run the 
extraction), and because fixing it requires digging into libclang, or 
creating a standalone reproducer to file the bug upstream (in the past 
I've not been able to do that), it's been shifted low on the priority 
list while I'm working on the foreign linker API.
