Ouch, I just reproduced this issue and all I can say is... ouch.

The problem is that the 64 bit version of the DLL has to be rebuilt
manually when the Cygwin version bumps.  At the time I created the
cyglsa package there was no Mingw 64 bit compiler available so I
used VC++ to build the 64 bit version.  However, I entirely forgot
about this problem when we bumped Cygwin to 1.7.1.

So the answer is, there is no way to get this working on 64 bit Windows
right now, other than to rebuild cyglsa64.dll manually under Cygwin
1.7.1.  I'll look into fixing this for 1.7.2 at least.  Maybe I should
remove the version lock.  There's no big chance that the communication
between Cygwin and the LSA package will change any time soon.
