Cannot compile anything - Getting compile errors from builtin.zig file

[rebb]

I want to try out zig, but can't seem to compile even the simplest zig files.
The hello-world example does not compile, neither does something that just has a main() function and nothing else in it.

The compile errors seem to come from a builtin zig file, and not my own code.

This is on windows, using the precompiled package ( fully unpacked etc. ).

I tried deleting the \stage1 directory a few times, after which zig rebuilds it. It does not help.

Here's some of the top errors, all errors are of this type :

One thing to note maybe, my UserData directory is a Windows Junction, so i can have my UserData stuff on a different partition.

I believe this was a problem with the caching system on Windows that is now fixed after the merge of #6250.
