true. didn't thought of that. very strange.

I'll step that in the debugger.

Cygwin can do symlinks for directories via the magic .lnk file.
But Cygwin can also do junctions via hardlinks in ln.exe.
I thought link() calls the junction code.
I'll investigate why the libc link() failed, and if ln.exe does some
sifferent magic, similar to pgsymlink.
