another new developer release: rc2

Hi

the last one had some minro problems... so here is a rc2 for 4.6.0. It
would be great, if we can get some feedback on how this one builds on
all your systems. Just a quick ./configure; make and perhaps a quick
game on FICS or against an engine ;) If you can test more, have a look
at the NEWS file or the one on the webpage

http://www.gnu.org/software/xboard/whats_new/4.6.0/

and check out the new features :)

Thanks

Arun
