Hmm, doesn't look my setting is working. Pretty sure it worked by just tweaking
this registry value on our servers, but if I check the group policy, it's states
as "enabled: no", and if I try to create a long path in PowerShell or Explorer,
it fails. So it doesn't seem like I have long paths enabled after all even
though the registry value is set. And as you state, the documentation also says
the application needs to register it.

I have only seen this on Hannes' gdb, not the one from mingw.
