Puppet users - Apr 2013 - What's my syntax problem: "Could not match 'c:/tmp' " ?

I assume I have a syntax problem of some kind. I created a class file and 
puppet complains on line 4.  If I remove that block of code it complains 
about the next block. What silly little mistake have I made?  The error 
reported for the code example below is:

        Could not match ‘george’, at 
/etc/puppet/environments/dev22/modules/custom_facts/manifests/virtuals.pp:4

class custom_facts::virtuals() {
  
  $tmp1 = $operatingsystem ? {
    /hello/       => ‘george’,
    /windows/ => ''C:/tmp'',
    default      => ‘/tmp’,
  }
  @file { ''tmp'':
       ensure => directory,
       path => "$tmp1",
  }
