Hi,

I just compile ruby readline ext for ruby 1.8.6-p110 now.  
However, when I run irb and include ‘ruby/completion’  
all my special character is not recognize by irb, like ‘Home’ become  
‘$’, arrow ‘\<-’ become ‘%’ and so on. Backspace is working fine and  
other alpha numeric character also work fine. It is still usable, for  
‘\<-’, I have to type which is not very inconvenience.

Anyone has any idea what I have making wrong?  
Base on the mkmf.log. I don’t have the tgetnum() function, anyone know  
how this impact to readline?

I get the readline src from:  
[http://jarp.does.notwork.org/win32/readline-4.3-2-src.zip](http://jarp.does.notwork.org/win32/readline-4.3-2-src.zip)
