[Bug-XBoard] bug 22812 fixed?

[Arun Persaud]

Hi

I just got the latest version of xboard from CVS and it doesn't compile on my 
machine with the errors in bug 22812 ( http://savannah.gnu.org/bugs/?22812) 
showing up. 

Managed to fix it  (at least it compiles and I can log into FICS again). I 
don't really know lex though, so it would be good if someone who understands 
the code has a look at it ;)

I had to change two things to get it to compile... capitalize yy_current_buffer 
and add a definitions for YY_PROTO.

Here is the diff (it's short, so I just cut&paste here):
