LyX-1.1.6cvs libsigc++

[Allan Rae]

I've updated libsigc++ in the stable branch.  It should be a bit more
cross platform/compiler happy now although I suspect that Sun CC still
won't be able to compile it.

Feel free to test it -- assuming you can get it.

BTW, has anyone else noticed that gettext-0.10.36 has been released?
Should we be updating that in 1.2.0cvs?  (I'm not volunteering BTW)
