Data types: char: 8; int: 32; long: 32; void *: 32; size_t: 32; off_t: 64;

What steps will reproduce the problem?

1. create symlink with absolute path on ftp server (for example pointing to /home/ftp/dir)
2. path must not exist on local system
3. connect to ftp by MC vfs
4. symlink is highlighed red, and you cannot open it
5. manually "cd symlink" is working

What is the expected output?
Just allow cd to such symlink.

What do you see instead?
I cannot enter symlink, but manually entering "cd symlink" works.

Example listing of FTP client entering such symlink:
