It seems that path separator normalization is not the only thing that is non-equal for symlinks. Finding out what is different...

[andrewrk]

If we take one of those examples, include/tkDecls.h, we see on posix the symlink data is:

../../System/Library/Frameworks/Tk.framework/Versions/8.5/Headers/tkDecls.h

however on Windows it is an absolute path:

C:/Users/andy/AppData/Local/zig/System/Library/Frameworks/Tk.framework/Versions/8.5/Headers/tkDecls.h

So this is actually #17461. That would actually make this fetch fail with the error "symlink points to outside of the package".

[andrewrk]

I extracted yet another issue from this into #17564.

[slimsag]

Just ran into this, nice to see there's a fix already in the works :D
