Patch did not apply correctly on extconf.rb with #2761 on ruby 1.8
Quoted from #2761
It seems that the patch have been partially applied. The extconf.rb stuff was not applied sot the weird behaviour still remains :
+# workaround for native windows.
+/mswin|bccwin|mingw/ !~ RUBY_PLATFORM && have_readline_var("rl_catch_sigwinch")

You seems to use Ruby 1.8.x.
So can you try following?

I've been noticing that irb (and as a result script/console in rails)
don't behave correctly with Control C. Nothing would happen when I hit
control C until I hit enter or a few more keys and then it would clear
the line and show a C and reset to the prompt. This doesn't happen on
Linux and it didn't happen on 10.5
If there's a long running process in irb hitting control c works as
expected but not if it's just sitting at a prompt.
I played around with the ext/readline.c and found that if I put a
rl_catch_signals = 0;
Then everything works as normal. Should this be added as a patch?
Reading the readline docs it seems to me that what's happening is the
internal readline handler gets stuck sending SIGINT back to the ruby
process even though there's a trap("SIGINT") defined. Any ideas?
