[MiNT] symlinks and hostfs

[Vincent Rivière <vincent.riviere@freesbee.fr>]

Hello.

I have noticed that symlinks are seen as regular files on hostfs :-(
This can be verified easily by using "ls -l"

In most situations, symlinks are normally treated as the file pointed 
to, except with the lstat() function used by ls.

The lstat() implementation is here:
http://sparemint.atariforge.net/cgi-bin/cvsweb/mintlib/unix/lstat.c?rev=1.2&content-type=text/x-cvsweb-markup
The implementation using MiNT syscalls is in __sys_stat()
http://sparemint.atariforge.net/cgi-bin/cvsweb/mintlib/mintlib/do_stat.c?rev=1.11&content-type=text/x-cvsweb-markup

Since Fstat64() does not seem to be implemented in hostfs, we fall back 
in Fxattr().

The implementation of Fxattr() is here inside sys_f_xattr():
http://sparemint.atariforge.net/cgi-bin/cvsweb/freemint/sys/dosdir.c?rev=1.27.2.2&content-type=text/x-cvsweb-markup

And unfortunately the parameter "flag" set to 1 indicating that the 
attributes of the symlink itself should be read is ignored :-(

Actually, I would be happy to use ARAnyM without any ext2 image, but 
these limitations are annoying.

Since the UNIX file API is provided by the MiNTLib and properly 
implemented in the hosts Linux/Cygwin/OSX, we should manage to get 
something satisfying...
