It does indeed support it (I think it's part of POSIX.1 compliance). 
Here's a little info:


-----
HISTORY
      The chown() function appeared in Version 7 AT&T UNIX.  The 
fchown() sys-
      tem call appeared in 4.2BSD.

      The chown() system call was changed to follow symbolic links in 
4.4BSD.
      The lchown() system call was added in FreeBSD 3.0 to compensate 
for the
      loss of functionality.
