This is the correct content of valid Cygwin Symlinks and for me
NT Explorer shows them as type "S" for symlink too.  The symlinks
should work fine from within any Cygwin based shell (bash, zsh, ...).

I remember having seen that on W2K and maybe XP, but on my

This is how a properly working symlink, created with ln -s,
> looks like:

IIRC, calling from cmd works with all kinds of symlinks on NT4,
I only got problems one time when building a windows version of
openssl on a W2K workstation.

As seen by 'ls -l':
lrwxrwxrwx    1 myname     mkgroup_       15 Dec 27 16:00 ar.exe -> /usr/bin/ar.exe

ls should show the same regardless which kind of symlink is used.

As seen by 'cmd /c dir':
27.12.04  16:00                    116 ar.exe.lnk

This is the hexlified contents of ar.exe.lnk:
00000000: 4c00 0000 0114 0200 0000 0000 c000 0000  L...............

00000070: 2e65 7865                                .exe

The Windows Explorer properly handles this as 'ar.exe',
a shortcut to H:\pub\cyg\bin\ar.exe.

I can't help it, but that's what I see. I have no idea whether this difference
in storing symlinks is a property of different Windows or Cygwin versions -
or whatever.

There are two kinds of symlinks, Windows style (with .lnk ending) and pure Cygwin symlinks, binutils obviously contains Cygwin stlye symlinks.
