Which way??? should remove or not??? TFM did not mention a single word on
symbolic links.

Yes. I DO want to know why. But TFM says nothing about errno. It only
mentioned that 0 is returned upon successful completion, and non-zero
otherwise. 

When I try to call remove(b) ('b' is a symbolic link to a directory 'a'),
perror prints:

remove: Not a directory

I still don't know why.
