I guess they care too much about portability to use "pragma GCC poison"?

Their whole "scheme", where ".." can be dealt with as a canonicalizing step BEFORE submitting the path to the OS for actual opening, seems to require refinement when symlinks are involved.

Take a perfectly spherical unix:

    $ mkdir /tmp/hn
    $ cd /tmp/hn
    $ ln -s . foo; mkdir bar; touch baz
    $ ls -l bar/../baz foo/baz foo/../baz
    ls: cannot access 'foo/../baz': No such file or directory
    -rw-r--r-- 1 jepler jepler 0 Nov 28 18:21 bar/../baz
    -rw-r--r-- 1 jepler jepler 0 Nov 28 18:21 foo/baz

Fuscsia-with-symlinks would have some extra hoops to jump through to make rewriting act like POSIX in the case that /tmp/hn is not escaped, which surely you'd want if you went ahead and introduced symlinks.
