X-Git-Url: https://git.netwichtig.de/gitweb/?a=commitdiff_plain;h=e9b652aa2a047557aaa1a68278d9d402f56d45b2;p=user%2Fhenk%2Fcode%2Fruby%2Frbot.git

ruby 2.0.0: fix for changed @waiters in compat19

I don't really know what this is all about, but this
fixes a bug with the compat19 monkeypatching. @waiters
is now a Hash.
